These are joined together by a single RBE2 in the middle and overall SPC'd at the rectangular edges. When I create a stress fringe plot from a load case, a summary of the max and min nodal stress is shown underneath the spectrum, such as: I have many load cases (50+) and I'd like to be able to just export the max stress and the associated node for each load case, perhaps in a .CSV for further post-processing. I'd like to do this for each group as well. How do I do this without actually looking through each load case and writing down the max stress? Previous attempts: I've attempted to create a report, select all of the load cases and relevant quantities, but the output seems to just grab the enveloping stress for n subcases, so this approach seems to not be the right path.Patranhttps://community.cadence.com/cadence_technology_forums/physical-system-simulation/patran/f/patran/74235/ever-wish-you-could-access-control-and-automate-patran-using-excel-now-you-can/1432615Wed, 25 Mar 2026 16:13:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:4a83695c-19b6-4b65-9b48-f6c10d938486Mitchell GreenbergThanks Sandip, I appreciate the feedback from someone at Hexagon.

Root Cause The error could be caused by duplicate Node IDs present in the list of nodes. Patran's RBE3 creation tool does not support duplicate entries, leading to the error. Solution To resolve this issue, follow these steps to clean up the node list and successfully create the RBE3 element: Create a Group to Remove Duplicates: Navigate to Group > Create in Patran. Add the node list into the group creation tool. Create the group. This group will not have duplicates Node IDs. Create the RBE3 Element: Use the cleaned group (via selecting "From Group(s)" button as shown below, or just cut/paste from the Group Modify menu) for the "Create Independent" Node List selection. Proceed with the RBE3 creation process as usual.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/patran/f/patran/74177/how-to-add-set3-card-to-bdf-using-patran/1432456Thu, 08 Jan 2026 09:57:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:5df8b69b-6961-47c6-a2a3-91cf778d7e4fEdwin GoeiHere's an article on how to write out SET3 from Patran: https://simcompanion.hexagon.com/customers/s/article/bulk-data-card-set3-for-elements-output-kb8024519 And here's an article on how to import SET3 cards into Patran to create groups: https://simcompanion.hexagon.com/customers/s/article/Nastran-SET3-Card-import-with-the-TABSCTL-card You will find the sample BDF in the article's "File(s)" section.

Select the Animation Control option. Set Up Animation: Use the Animation Control to configure the animation settings for the Isosurface. Adjust the parameters to suit the desired animation effect. Playback Options: Once set up, you can play the animation directly within Patran. Note that Patran does not support saving animations in modern formats like MP4. Recording the Animation: To save the animation, use your own screen recording application to capture the playback. A simple video demonstration of this process can be seen below: nexus.hexagon.com/.../insight_5F00_animation.mp4 For more detailed instructions, refer to the Patran Insight Control Documentation .https://community.cadence.com/cadence_technology_forums/physical-system-simulation/patran/f/patran/74091/how-to-create-cbend-pbend-for-a-curved-tube-in-patranTue, 14 Oct 2025 17:46:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:a782f96e-9e50-47c3-b8d2-6d660501595dEdwin GoeiQuestion: How to create CBEND /PBEND for a curved tube in PATRAN? I want to define curve tube outer/inner radius (or mean radius + thickness), and bend radius as well as a FSW of 2 for the stress intensification method. Answer: To create CBEND elements with PBEND properties for a curved tube, you'd use the "Curved with Pipe Section" option as shown below.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/patran/f/patran/74050/fastener-builder-patran/1432196Thu, 18 Sep 2025 00:56:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:a4f60e26-3dc3-4325-8692-c6b2f569041fRaffaele FerraraYes, I know but unfortunately I have to use Fastener Builder v2.0.

I couldn't find any load_vector / node type function. In order to get the plot you want it seems you need to add a custom result to the DB. I know you rather not modify the DB, but you can always delete the result case once you are done with it (deletion code is included in first function to not duplicate result cases). If you put the following code in a class, you can run the test_vector_plot() function (assuming you have a FEM with nodes 7-12: FUNCTION create_nodal_vector_result(tit1, tit2, nnodes, nodeIDs, results, res_ids) /* INPUT: tit1, tit2 string[80] - Primary and Secondary Result titles nnodes - integer - number of nodes nodeIDs(nnodes) - integer - the node IDs results(nnodes, 3) - real - result vectors OUTPUT: res_ids(5) - pass in as INTEGER res_ids(5), save this to use for delete if desired */ STRING tit1[], tit2[] INTEGER nnodes, nodeIDs(), res_ids(), datatype = 2 /* vector */ REAL results() INTEGER status, secID STRING lc_title[80] = "Nodal Vector", sc_title[80] = "Custom" /* Delete existing if exists, so don't built multiple */ res_ids = [0,0,0,0,0] res_utl_clear_result() /* clean up any old stuff */ db_get_load_case_id(lc_title, res_ids(1)) IF (res_ids(1)!=0) THEN db_get_sub_case_id(res_ids(1), sc_title, res_ids(2)) res_db_cdeleterescases( 1, res_ids(2:2) ) END IF /* Docs for res_utl says res lc & sc & layer must exist */ /* layers require a section */ REAL coords(2,2) /* dummy not used */ dbt_create_sect_pos(1, "", 0, coords, secID) /* create a layer */ dbt_create_layers(1, 0, secID, res_ids(5)) res_db_create_loadcase_c(lc_title, 1, "Describe Nodal Vector", res_ids(1)) res_db_create_subcase_c(res_ids(1), sc_title, res_ids(2), secID) /* undocumented */ dump res_ids status = res_utl_create_nodal_result(res_ids, tit1, tit2, nnodes, nodeIDs, "", datatype, results) dump status END FUNCTION /* ------------------------------------------------------------------------- */ FUNCTION show_nodal_vector_result() /* need customization */ res_data_load_dbresult( 0, "Nodal", "Vector", "Nodal Vector", "Custom", @ "My Title1", "My Title2", "(NON-LAYERED)", "", "AsIs", "DeriveAverage", @ "All", "ShapeFunc", "", 0. ) res_data_title( 0, "Nodal", "Vector", 1, @ ["$POFF@@@$PT: @@@$LCN, @@@$SCN, @@@$PRN, @@@$SRN, @@@$DRVL, @@@$LN"] ) res_display_vector_create( "", "Nodes", 0, [""], 17, @ ["Range:Vec_default_Vector", "RangeOverwrite:ON", "VectorDisplay:Resultant", @ "VectorComps:ON", "VectorColors:Spectrum", "VectorScale:ScreenConstant=0.1", @ "VectorAttachment:Head", "HeadStyle:Single", "VectorStyle:Solid", "TailDisplay:ON", @ "TitleDisplay:ON", "MinMaxDisplay:ON", "LabelStyle:Exponential, 12, White, 3", @ "ValueDisplay:ON", "Filter:Exclude=-1e-36,1e-36", "ScaleFactor:1.", @ "RelativeToGeom:ORIG"], TRUE ) res_display_vector_post( "", 0, "Nodal", TRUE, TRUE ) END FUNCTION /* ------------------------------------------------------------------------- */ FUNCTION test_vector_plot() INTEGER resIDs(5), nnodes = 6, nodeIDs(6) = [7,8,9,10,11,12] REAL vec_results(6,3) = [ @ [0.,0.,1.] @ [0.,0.,2.] @ [0.,0.,3.] @ [0.,0.,4.] @ [0.,0.,5.] @ [0.,0.,6.]] THIS_CLASS.create_nodal_vector_result("My Title1", "My Title2", nnodes, nodeIDs, vec_results, resIDs) THIS_CLASS.show_nodal_vector_result() dump resIDs END FUNCTION /* ------------------------------------------------------------------------- */ It will give you something like: Hope this helps.

But for vector, there should be a function corresponding to res_data_load_elem_scalar( 0, table_id ). Maybe it has a name res_data_load_node_vector( 0, table_id ). What I want now is the exact name of this function. I prefer to use the method of not creating any objects in Patran. So creating a loadcase is not the best way for me. Thank you all the same.https://community.cadence.com/cadence_technology_forums/physical-system-simulation/patran/f/patran/74045/how-to-create-vector-results-using-pcl/1432189Fri, 12 Sep 2025 13:07:00 GMT75bcbcf9-38a3-4e2e-b84b-26c8c46a9500:36a8f817-5b79-4f1d-b0ca-cfde503bd7d1Mitchell GreenbergI only recall creating plate element fringe plots (based on method observable by !!TRACE calls nostdout of Properties->Show->Thickness->scalar plot, but the vector plot at nodes should be similar. In order to use the result tools you need to create the result, the plot and then post it. Here is the way to create and post a scalar plot: FUNCTION show_custom_scalar_fringe(eids, etopo, sca_data) INTEGER eids(), etopo(), nelems, table_id REAL sca_data() IF (sys_array_nbound(eids)==0) THEN RETURN nelems = sys_array_hbound(eids,1) ga_elem_scalar_single_create("sca_data", nelems, eids, @ etopo, sca_data, table_id) res_data_load_elem_scalar( 0, table_id ) res_display_fringe_create( "", "FreeFaces", 1, ["EL:Elm 1:#"], 12, @ ["Range:default_Fringe", "RangeOverwrite:ON", "FringeStyle:Discrete/Smooth", @ "Shade:None", "ElemEdge:None,Blue,Solid,1", "Shrink:0", "TitleDisplay:ON", @ "MinMaxDisplay:OFF", "ValueDisplay:OFF", "Filter:None", "ScaleFactor:1.0", @ "LabelStyle:Exponential,12,White,3"], TRUE ) res_display_fringe_post( "", 0, "ENodal", TRUE, TRUE ) REPAINT_GRAPHICS() END FUNCTION To do similar with vector try: ga_node_deform_create() instead of ga_elem_scalar_single_create() try: res_display_vector_create() instead of res_display_fringe_create() result_display_vector_post() instead of res_display_fringe_post() Good luck. If you can't get this to work, you could also consider creating a nodal FEM field with your node/vector data (fields_create_dfem), use it to create a loadcase (loadsbcs_create2) and display the loadcase vector plot (loadsbcs_plot_markers_v2). There are more complicated methods beyond this, but hopefully this will get you on the right track.
