Both as long as there is a database of images provided which allows to train the model. However, as of 2025.2, it is not possible for ODYSSEE A-Eye to perform these operations in-live within the manufacturing process.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/74090/can-odyssee-a-eye-perform-default-detection-and-classification-in-liveTue, 14 Oct 2025 09:57:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:722bed32-6c00-4e05-b5ef-28e4d5b7e00aDenis BuissonI have freshly manufactured parts conveyed accross the plant and photographed. Is ODYSSEE A-Eye capable of identify defaults on the parts and classify the defaults in-live as they go through the conveyer?https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/74076/odyssee-cae-data-manager-advanced-capacities/1432250Fri, 03 Oct 2025 10:31:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:c3efa275-edd5-4dfb-bf7e-12f42fff5627Denis BuissonTo create an ODYSSEE CAE project, it is important to have X data and Y data clearly identified. The X corresponds to the parameters of the model studied, while the Y corresponds to the output channels of the model analyzed. The X and Y data can be paired with some Xval - Yval data, i.e. some validation points which can be used as test cases to increase the model's prediction accuracy. All this data can be loaded from several .csv files, or from a single one with everything merged inside it. And thanks to the Data manager, it is possible to assign correctly which data is what and where should it go. In the below screenshot from the main interface, we can see on the left the Data manager, and in particular the tree/hierarchy organization for the different data X, Xval, Y and Yval. In this case, each data is saved in a dedicated .csv file. However, it is possible to load several files, each one containing only some (or simply one) case, as shown in the below screenshot: In this case, instead of loading one file containing the 15 result curves, there are 15 files loaded each one containing one result curves. These files are imported under the relevant branch of the tree as data sources. When clicking on a data source, the cells selected to be part of the final data are highlighted in green. It is possible to click on the corresponding branch to display the final that has been selected and collected within the data sources. This allows to define the data even if it is spread out into different files for each case of the database. It is important nonetheless that all the curves have the same number of points to enable the software to concatenate the data selected. On the opposite, it is also possible to organize the data even if it is merged into a single file. To do so, after selecting the data source, a right-click on the desired data will propose several options to easily select or deselect part of the data source, or move it from training part (X or Y) to validation part (Xval or Yval, respectively) or the opposite. It is also proposed to create a new Y output channel from the data. In the above screenshot, we have selected two rows to use as validation cases. The outcome is presented in the screenshots below: The two rows are unselected, and will not be used for training, and we can see that the data source has been copied into the Xval branch. If we click on it, we can see that only the two relevant rows are selected for validation, as visible in the screenshot below: This works within all branches of the Data manager: X, Xval, Y and Yval.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/74076/odyssee-cae-data-manager-advanced-capacitiesFri, 03 Oct 2025 09:01:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:4881abd0-16ef-404b-aeaa-6a8c4177bec4Denis BuissonLet's say my X and Y data is spread out into several .csv files, or merged into a single one. Can it be imported into ODYSSEE CAE nonetheless and can I create my project despite that?https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/74070/how-to-create-a-new-project-in-odyssee-cae/1432237Mon, 29 Sep 2025 10:59:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:5cd80050-f8ad-410d-b292-37917e852021Denis BuissonOnce the DOE has been generated, the X data is ready, and as soon as the models/simulations corresponding to the DOE cases have been computed and their results have been collected into .csv files, the Y data is ready too. We will use the X and Y data to create a new project in ODYSSEE CAE. When the tool is launched, here is how the interface is presented: The top band indicates the order of the manipulations recommended to follow. In the step 1-Project, the top-left button allows to create a new project. When clicking on it, a window opens: In this window, there are a few fields to complete the project creation: type in the project name, specify the working directory (where your X and Y files are stored), and choose the location for the ODYSSEE CAE project folder (where ODYSSEE CAE will save its files). The ODYSSEE CAE project folder can be saved in a default path for all ODYSSEE CAE projects, or it can be saved in your working directory, close to your original data. Once this has been configured as desired, and button "OK" has been pressed, the project is created, and the Data manager automatically opens to complete the X part of the data. Within it, you can import your DOE .csv file thanks to the corresponding button. If you have an Xval file with some validation cases, you can also import it. To complete the Y part of the data, click on the "Y-YVAL Data" button in the Data manager tree. You can now press the button "import Datasets from Csv" and select the different result files, with one output channel/type per dataset. If you had imported validation cases for the X part, you will also need to import the corresponding Yval files. Before validating the data configuration, as soon as the DOE has been input to the software, it is possible to press the bottom left button "check data", which will look for eventual dependencies between the parameters and duplicated cases within the DOE, which should be removed before going further. Indeed, dependencies and/or duplicated are prompt to cause bad prediction results or generate errors. Once the X and Y data has been configured as wished, pressing the "validate data configuration" button will close the Data manager and display the datasets in the main window. To re-open the Data manager and re-configure the input data, you can press the top button (with a wrench) in step 2-Data of the top band. For more information and advanced techniques about the Data manager and data filling/completion, a dedicated thread will be opened.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/74070/how-to-create-a-new-project-in-odyssee-caeMon, 29 Sep 2025 09:50:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:9aa6af64-41fc-44d6-a54f-a27da466771fDenis BuissonI have generated a DOE, I have created the models/simulations corresponding to the cases of my DOE, and I have collected the computation results from the different cases. Therefore, I have my data ready: the DOE consitutes the X part, while the results collected from running the models/simulations composes the Y part. Now how should I proceed to create a new project in ODYSSEE CAE using my data to start my analysis?https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/74054/after-running-the-simulations-how-to-collect-the-results-of-the-multiple-models/1432199Thu, 18 Sep 2025 10:53:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:8c7ad63a-51d6-48f7-848a-f7c3baa7f2fcDenis BuissonOnce all the simulations corresponding to the DOE have been executed successfully, not only we want to collect the results of each model run, but we also want to group the results together in an organized way, so that we can load these correctly into ODYSSEE. The goal is to create one or several .csv files: each .csv file will contain the results for one output channel i.e. one particular result type. In each .csv file, the most common convention is to write the relevant result on a row for each simulation executed. As a consequence, at the end of the extraction process, all output .csv files will have as many lines as the DOE. To do so, we use the same tools as for creating and run the multiple models with different parameters values, as presented in this thread: How to create and run multiple models, each with different parameter values? - ODYSSEE Community Forum - ODYSSEE - Nexus Community The parsing tools not only allow to create and run the multiple models with different parameters values, they also allow to extract the results from the simulation output files, collect these, and group them together and write the corresponding .csv files, ready to be loaded into ODYSSEE and get started working on one's project with these. ODYSSEE proposes several parsing tools depending on the solver used to run the simulations: Nastran parser tool, to extract results from Nastran simulation output files under .h5 format LS-Dyna parser tool, to extract results from Ls-Dyna simulation output files under glstat, nodout, jntntforc, rcforc, rwforc, deforc, abstat, matsum, sbtout, nodfor, secforc, tprint, elout or dbfsi format Adams Car parser tool, to extract results from full-vehicle Adams Car simulations Pulsar generic parser tool, to extract results from any ASCII format output file Adams Results extraction tool, to extract results from Adams simulation output files under .res format The principle is often the same: Select the working directory, template model file and DOE. This is prepared in the Project setup section at the top left of the tool Configure the output channels to extract within the simulation results files, and eventually precise the desired nodes ID and min and max timestamps to extract. This comes right after (below) the Substitution setup, in the Extraction step section, at the upper middle left of the tool The output channel selection is based on keyword identification and output file hierarchy. Once the extraction is configured, click on "Run" at the middle bottom of the tool. This will create within the working directory as many .csv files as there are output channels requested in the configuration, and each .csv file will contain as many rows as there are Mi folders i.e. as many cases present in the DOE file. Each M folder will also contain the .csv files corresponding to the results that have been extracted from the relevant simulation run. The Nastran parser tool configuration (above) and LS-Dyna parser tool configuration (below) are almost identical. The Adams Car parser tool configuration is slightly different, as the user can extract only scalar objective output results. Pulsar generic parser tool is an independent tool which allows to extract data from any ASCII format file. The extraction is configured by position within the file: the user must select the field to extract, and can set a writing format for the value to be collected. Adams Results extraction tool is meant for extracting results from Adams .res files, completing thus the Adams Car parser tool. It also proposes options to re-interpolate curves or pad files so that all results of the output channel have the same number of points. Indeed, regardless of the nature of the data, output type or origin, it is important that all the simulations have the same number of points/columns for a same output channel, since ODYSSEE does not handle curves of a same nature/type with different lengths. However, between different output channels, the number of columns can be different: some output results from a first channel may be simple scalar values (in such case, the corresponding .csv file will contain a single column), some other output results from a second channel may be time-dependent curves with several points (corresponding to the measuring points along time - in such case, the corresponding .csv file will contain as many columns as measuring values).https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/74054/after-running-the-simulations-how-to-collect-the-results-of-the-multiple-modelsThu, 18 Sep 2025 10:11:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:7379a777-643f-49f3-902f-4881627cad8fDenis BuissonI have created a Design Of Experiments (DOE) which contains combinations of parameter values for the parameter(s) of my model that I want to study. I have created copies of my template model where I have updated the parameters values inside it with the values of my DOE. And finally, I have run the created models corresponding to these parameters values combinations coming from the DOE. I am now looking for a way to collect the results of all these multiple simulations, so that I can load them in ODYSSEE CAE and start my project with these. How should I proceed?https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/74033/is-there-a-way-to-establish-a-relation-condition-restriction-among-the-parameters-of-a-doe-at-odyssee-cae/1432178Thu, 11 Sep 2025 11:00:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:4e65922d-e53e-436f-9c29-96edc0c941afDenis BuissonHello Alejandra: Here is another idea regarding your need to establish a condition between the parameters in a DOE which works for your problem (p1 > p2 > p3 > p4) You can keep p1 as it is, but for p2, you replace its value by the difference between p1 and p2, for p3 you replace its value by the difference between p2 and p3, and for p4 you replace its value by the difference between p3 and p4. Applied to the DOE you shared in your initial question, here is the resulting matrix after updating following the above solution: p1;p2;p3;p4 8.1;-1.3;-3.6;-1.7 4.6;2.9;-2.4;4.2 Then you should remove the cases where p2 or p3 or p4 is positive. I leave it to you to check if it works for your problem statement, you may also have min and max values for each of your parameters that must be respected, and should then be verified. Afterwards you can work with this updated DOE or transform the values back after checking all conditions are respected I hope all this clears things up and helps, and I hope that it makes sense and works for you. If it does not, or if you have any further questions, doubts, or concerns, inquiries, let me know.

The best in such case is to generate a DOE larger than desired, and remove the points that do not respect the desired constraint. However this approach is not perfect neither, because it outbreaks the DOE homogeneity. We have a Quasar script that allows to automatically perform the manual operations presented above. You can find it in the ODYSSEE Solver / Quasar Examples document, which is available in your personal Documents directory, in the subfolder Odyssee\CAE\Examples\Quasar (default : C:\Users\username\Documents\Odyssee\CAE\Examples\Quasar). The relevant section is Advanced Examples > DOE with constraint > Generate a DOE with constraint. This section is followed by an example. The button "Configure from file" is not meant for receiving a Quasar script, but a .csv file. This .csv file has a particular format so that when loaded it automatically completes the parameters table in the DOE generator. The appropriate format is the following: parameter1Name;parameter1MinValue;parameter1MaxValue parameter2Name;parameter2MinValue;parameter2MaxValue parameter3Name;parameter3MinValue;parameter3MaxValue Attached is an example of such .csv file : nexus.hexagon.com/.../doeConfigFile.csv I hope all this clears things up and helps, and I hope that it makes sense and works for you. If it does not, or if you have any further questions, doubts, or concerns, inquiries, let me know.

The first point of the DOE has as values the following: p1=8.1 p2=6.8 p3=3.2 p4=1.5 While the second point has as values the following: p1=4.6 p2=7.5 p3=5.1 p4=9.3 The physical model where the parameters came from, has a geometric restriction where p1 > p2 > p3 > p4, so the parameters values of the second point are not "valid" for the analysis of the physical model. At the DOE generator tool there is a button called "Configure from file". I guess the solution implies to create a quasar script and import it using the "Configure from file" button, but I didn't find info about it. Is there an example of how to do it?https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/73937/how-to-create-and-run-multiple-models-each-with-different-parameter-values/1431900Mon, 23 Jun 2025 10:23:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:91b27e9f-f607-43cc-9386-212499bac290Denis BuissonYes, the solution for this is to use a parsing tool. ODYSSEE proposes several parsing tools depending on the solver used to run the simulations: Nastran parser tool, for Nastran models under .bdf or .dat format LS-Dyna parser tool, for Ls-Dyna models under .k format Adams Car parser tool, for full-vehicle Adams Car models Pulsar generic parser tool, for any ASCII format file Adams Results extraction tool, for Adams results files under .res format The principle is often the same: Select the working directory, template model file and DOE, and configure the solver. This is prepared in the Project setup section at the top left of the tool Configure the parameters to replace within the model chosen, and link them with the parameters of the DOE. This comes right after (below) the Project setup, in the Substitution step section, at the upper middle left of the tool The model parsed is displayed on the top right of the tool, and the parameter to be parsed is highlighted within it. The parameter selection is based on keyword identification and model hierarchy. Once the parsing is configured, click on "Run" at the middle bottom of the tool. This will create within the working directory as many Mi folders as they are cases in the DOE file, and each M folder will contain a copy of the template model file with the parameters values inside it updated with the values of the DOE. If the solver is configured, the models will be automatically executed one after another. The Nastran parser tool configuration (above) and LS-Dyna parser tool configuration (below) are almost identical. The Adams Car parser tool configuration is slightly different, as the user inputs a Car database folder, Event file and Experiment file instead of a single model file. Pulsar generic parser tool is an independent tool which allows to parse any ASCII format file. The parsing is configured by position within the file: the user must select the field to parse, and can set a writing format for the value to be updated. Adams Results extraction tool is meant for extracting results from Adams .res files after simulations have been run. It will be detailed in a topic dedicated to results extraction.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/73937/how-to-create-and-run-multiple-models-each-with-different-parameter-valuesMon, 23 Jun 2025 09:29:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:2361a224-bfae-4556-9c30-7a3d45a9179fDenis BuissonI have created a Design Of Experiments (DOE) which contains combinations of parameter values for the parameter(s) of my model that I want to study. I am now looking for a way to easily create a copy of my template model and update the parameters values inside it with the values of my DOE.

To access it, either click on "DOE" button in the main ribbon, or click on (top-menu) > Tools > DOE generator A new window appears Focusing on the Generate DOE section on the left, you can Add one or several parameter(s) depending on the number of parameters of your system. For each parameter, you can specify its name and min-max values. Finally, you can click on "Generate DOE" button to create the parameters values combinations. Going further, you can change the number of points to generate, as well as the DOE generation algorithm to use. You can also visualize the points of the DOE thanks to the scatter plots, as well as in PCA (Principal Component Analysis) scatter plots. When working on the DOE generation, there are some important points to keep in mind: The number of parameters and their ranges directly drive the size of the domain. If it is too small, the model will not allow much variation. If it is too large, it will be difficult to predict, a lot of sample points will be required to capture the system behaviors. The number of points drive how dense the domain is covered. If it is too small, the model may not be able to predict easily with a good level of accuracy. If it is too large, the model will take more time to predict. Depending on the system studied, some zones within the DOE may require more points to focus on a region which is more interesting for final processing, or where prediction might be more difficult due to versatile behaviors. DOE scatter plots and PCA scatter plots are useful to help to visualize the distribution of the points of the DOE generated.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/73922/how-to-generate-a-design-of-experiments-doe-in-odyssee-caeMon, 16 Jun 2025 07:49:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:47826c9f-b5be-4af4-bbc9-8d4d37062021Denis BuissonOnce I know what are the parameters of my system, where and how to generate a Design Of Experiments (DOE) in ODYSSEE CAE ?https://community.cadence.com/cadence_technology_forums/physical-system-simulation/odyssee/f/odyssee/73921/how-to-get-started-in-odyssee-cae-when-i-do-not-have-any-data/1431865Mon, 16 Jun 2025 06:39:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:162c9c90-553a-4c09-8ef9-54f99127bb91Denis BuissonBefore even opening ODYSSEE CAE, the first thing to do is to think about the problem you are studying, and state it so that it is clear: What is the system analyzed? How does it overall behave? What are the parameters in input? What are the responses in output? How is the system modeled? (Finite Elements simulation, physical experience...) What is the final goal to achieve with the predictive model? (Export as FMU, look for an optimal result, predict animations...) It is very important to have a clear vision of the problem studied so that it can be easily stated and configured in ODYSSEE CAE.

In particular, ODYSSEE CAE GUI examples are saved within this subfolder, in Lunar\examples (by default: C:\Program files\ODYSSEE\CAE\Documentation\Lunar\examples ). However, since installation directory often requires administrator privileges for writing and editing files and directories, a copy of the Documentation folder content is made in the user's default Documents directory, in ODYSSEE\CAE\Examples subfolder (by default: C:\Users\username\Documents\ODYSSEE\CAE\Examples ). Once more, in particular, ODYSSEE CAE GUI examples are saved within this subfolder, in Lunar (by default: C:\Users\username\Documents\ODYSSEE\CAE\Examples\Lunar ). This copy is created when the user launches the ODYSSEE CAE GUI for the first time. Since this copy is stored within the user's personal directory, its content can be modified as the user wishes without needing any administrator privileges, and new files can be written there as well.
