There is no specific setting for the desired unit system in the MD library. Rather, the MD library will use the unit system selected from the other library(ies) already present in the model. For example, if there are HC library components in the model, and the FP(HC) component specifies the Metric unit system, then any MD library components will also use the Metric unit system. This KB article gives more information about usage of the new MD library: https://simcompanion.hexagon.com/customers/s/article/Usage-of-the-new-Multibody-Dynamics-MD-library-in-Easy5https://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/73960/where-to-specify-the-unit-systemTue, 08 Jul 2025 08:44:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:4c3a73b0-7dd5-4a49-a8c4-d6ce49f9c067Rishikesh MokashiHi , In my model, I am using a mass dynamics component from the new MD Mass Dynamics library in Easy5 2025.1. I know I can specify which unit system that the MD library uses, but I don't know where to specify that. Can you tell me where to find this setting?https://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/73877/dll-file-generated-by-ez5-in-adams-mechatronic/1431786Tue, 20 May 2025 13:09:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:439274be-7517-4d61-8ecb-1a5a5846cea5Rick ClantonThe issue is that none of the Easy5 environment variables exist in the Adams environment. It needs those to find the Easy5 files. Try this: Close Adams. Open an Easy5 Command shell either from the Start menu shortcut, or from the Easy5 GUI under the File menu. In the Easy5 Command Shell (which contains all the necessary Easy5 environment variables), start Adams using the command line syntax: adams2024_2 aview ru-s i Then open the Adams model and retry the workflow. Now Adams should know where to find all the Easy5 files.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/73877/dll-file-generated-by-ez5-in-adams-mechatronicTue, 20 May 2025 10:54:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:c43474fd-52e9-46b9-9cf1-c44ff25df279Ghasem AbbasnejadI am trying to use dll file generated by EZ5 in Adams Mechatronic.

Product development has added this feature in the next version of Easy5. This will be integrated into the existing IR integrator in the GP library. The integrator reset will be configurable to be either internal or via an external trigger input. If you need access to this capability sooner, please let me know by sending me a DM, or opening a support case via SimCompanion or sending an email to easy5.support@mscsoftware.com.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/73761/integrator-reset/1431491Wed, 22 Jan 2025 14:01:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:68503f9a-f0c5-4353-b811-900cfbeb8911Rick ClantonThere is currently no way to do this with the built-in components. However, it may be possible using some customization.

When the error signal crosses zero (changes sign), I would like the integrator to reset to 0 (my valve opens fully) I don't know if this is a valid control approach. I saw an integrator with reset in the general library, but the reset trigger can not be connected to another signal (like error) Is there a way to reset an integrator from an outside signal, or should such things not be done. thankshttps://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/73603/hello-everyone-in-my-project-i-used-composition-poppet-type-in-the-valve-however-easy5-have-two-type-poppets-cone-and-ball-may-i-make-composition-poppet-in-easy5-best-regards-samet/1431098Thu, 11 Jul 2024 11:12:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:5feeb1a6-07da-440e-a8a7-e693b068b6d5Rick ClantonYou are on the right track for sure. Some questions: 1) You have several flow multipliers in the model. Does this mean that there are multiple copies of the poppet valve pairs that are acting on the same actuator? 2) Where is the actuator feed pipe connected to (the piston side or the rod side of the actuator)? 3) Is the feed pipe gate controlled by the piston movement or is it controlled by another separate poppet? 4) Are the gas recharge and discharge poppets controlled by the same solenoid or two different solenoids? 5) You have two PI components in the model to consider water hammer. Do you specifically want to consider that? If so, that is the correct component to choose. Otherwise, I would use PR instead. Using PI will make your model less robust and run slower than using PR. 6) What version of Easy5 are you using?https://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/73603/hello-everyone-in-my-project-i-used-composition-poppet-type-in-the-valve-however-easy5-have-two-type-poppets-cone-and-ball-may-i-make-composition-poppet-in-easy5-best-regards-samet/1431094Thu, 11 Jul 2024 00:09:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:829d5ddf-3421-475b-ba44-04d7f0791756samet.gonerHi Rick, Thanks a lot your advice. I will apply first option. However, I have a bigger problem:). I shared system schematic diagram and easy5 model as attachment file. I start to explain the case: Pressure Vessel gas recharge period; selenoid system open the poppet valve and gas flow inside the vessel chamber. In vessel chamber, gas flow into the check valve to the big volume chamber in the vessel. Pressure vessel gas Decharge period: Unbalance pressure is vessel and piston move to below. Then open the actuator feed pipe gate, high pressure gas go to the actuators. I try to make 1 d model in easy5 software. However I need your support for make true model.

I would suggest one of two options. 1) Create a table of flow area vs. poppet stroke and put that in the model where you would have put the PA. or 2) Use a FO Fortran component to put in the flow area equation (area=pi*seat_dia**2*stroke) to calculate the flow area for a given seat diameter and the variable stroke. That would go where the PA would normally go.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/73603/hello-everyone-in-my-project-i-used-composition-poppet-type-in-the-valve-however-easy5-have-two-type-poppets-cone-and-ball-may-i-make-composition-poppet-in-easy5-best-regards-sametWed, 10 Jul 2024 01:28:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:1e9cb997-1034-4d53-ad66-7874ce461900samet.gonerHello Everyone, In my project, I used composition poppet type in the valve.

I tried again, after failing so many times before with those same steps and it worked. I think the difference was you noted select "Run" which wasn't the option given to me by VS. It presented "Start". Choosing "Start Debugging" from the Debug menu seemed to be the key I was missing. Thank you. I have shown my steps below. 1) Open model 2) Build -> Debug Mode (checked) 3) Build -> Create Executable (Mode executable created successfully (for use in debug mode), build log confirms) 4) Analysis -> Execute/Debug (VS launches) 5) From VS File -> Open -> .f (not .datain.f) 6) Scroll down to first assignment line past all the variable declarations and such, assign breakpoint 7) Debug -> Start Debugginghttps://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/72586/how-to-debug-easy5-with-visual-studio/1428109Fri, 20 Aug 2021 08:07:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:a7135dfa-19c7-43e0-b437-0b34afbe4e45Rick ClantonYes, when you start the debugger, you will need to manually load the modelname.f file. Then you can set the breakpoints in the code (subroutine EQMO). So just to be sure you are doing things correctly, here's the procedure: Turn on Debug mode in Easy5. Compile the model in debug mode Run the analysis in debug mode. Visual Studio will launch. Set the exception handling options if needed. Manually open the modelname.f file Right click on the first line of the code (Subroutine EQMO) and set a breakpoint Set any other breakpoints in the code you desire. Select the Run or Continue button The debugger should then step through the code. Try this again and let me know at which point this fails for you.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/easy5/f/easy5/72586/how-to-debug-easy5-with-visual-studioThu, 19 Aug 2021 10:01:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:49019992-910e-4fbc-9410-d3f76a2a9fb9matthew.goitI have the following installed (this is also the order of installation) Intel Fortran 2017, Visual Studio 2017 and Easy5 2018. Easy5 compiles with the intel compiler using either the standard or debug options. When I compile with debug I can analyze using the "Debug the current analysis" button and Visual Studio launches. When VS loads the "Start" button is available but the source code is not. VS can display the assembly if desired but that is not useful for me. The users guide says I should open the source file that is named .f. This file can be opened fine in the IDE but the debugger doesn't use it. I can't set breakpoints in eqmo that actually work. Upon pressing start the program will run and exit without triggering the breakpoint.
