  1. Hello @Rahul R Thank you for your reply. The loading curves that I am using are provided by the supplier. An analysis using these curves was conducted previously on ABAQUS and a proper results were obtained. However, I believe, since the input deck for optistruct and abaqus differ considerably, some error might have crept in while defining the model in optistruct. Since I am not allowed to send the global model I am working on here, I have created a simplified model of a gasket sandwiched between two blocks. The gasket properties have been kept same as the global model. I am also attching the excel sheet of the gasket loading and unloading curves provided by supplier. Could you please go through this model and the curves and let me know what mistake I am making. Regards Puneet, gasket curves.xlsx gasket _altair forum.fem
  2. Hi, I am performing an analysis using gasket materials. However, I am encountering the following error: *** ERROR # 4704 *** The loading path must start from the origin. MGASK #15 (BEHAV = 1). *** Run terminated because of error(s) in the input data. All the loading and unloading curves start with zero pressure and at zero clearance as shown the pics. Unfortunately, I am not allowed to share the model. Could someone identify the cause of this problem? Thanks in advance.
  3. Hi, I am trying to convert a thermal analysis model setup in abaqus into optistruct using, TOOL-> Convert command. However, I am ancountering th e following error:
  4. @Rahul R thanks for the reply. this is a test case, later on I will be optimizing desiel power train. It is not possible to assign stress and displacement constraint on that model. Anyway, the objective is to increase the stiffness by reducing the volume or weight by 80 to 70%. That is the reason I am trying out the test case in this way. is it not possible to assign weighted compliance to mechanical loadstep in thermo-mechanical analysis? I am attaching the latest files of thermo-mechanical analysis for both weighted compliance and thermal compliance along with a ppt for better clarification.

  5. Hello, I am trying to run an Thermo mechanical optimization on a simple cuboidal model. The results that I am getting from only analysis and later optimization are varrying considerably. Could someone here identify the problem? 10th sept_wcomp with fux_A2.out 10th sept_wcomp with fux_A2.h3d 10th_sept_wcomp_with_fux_A2.fem 10th sept_wcomp with fux_opt_s2.h3d 10th sept_wcomp with fux_opt_s1.h3d 10th sept_wcomp with fux_opt_des.h3d 10th sept_wcomp with fux_opt.out 10th sept_wcomp with fux_opt.h3d 10th_sept_wcomp_with_fux_opt.fem
  6. @Rahul R As suggested, I have run the same setup for thermal compliance. This is the out message that I received. 10_sept_single_solid-single_surfac_conv_TMTC_0.7_opt.fem 10 sept_single_solid-single_surfac_conv_TMTC_0.7_opt.out
  7. Hi, I am trying to run a test thermo-mechanical optimization on cuboidal component. I seem to get a weired results. materials are being removed from those places where stresses are high (maximum). Could someone go through the results and the model file and help me in understanding the mistake that i am obviously but unknowing committing?

  8. Hello @Rahul R Thanks for sharing the model. I am going through the entire course on thermal analysis, I am able to download and use the files of pdf tutorials, however, I can not find the location of the models refered in ppts. Could you kindly share with me the link for the model_files or share the folder itself. It would be of great help. Thanks in advance.
  9. I am not able to find the model_files refreed to in the online courses. someone here has the link for those files?
  10. @Rahul R However, I could find the elements (e.g. element #7008278) using the Find element tool. I also tried to delete the contact surfaces and apply loads directly, now I am get the error that ERROR 14: Missing element #----referenced by PLOAD4 # 2.
  11. Solver- optistruct I am getting the error 14 for every contact surface. It says - *** ERROR 14: Missing element #7008278 referenced by SURF # 30. I have tried creating the contact surfaces again on these elements, but the problem persists. There are overall 25260 such elements ( basically all the elements attached to the contacts surfaces). does anyone here has the solution for this? error msg ------ *** ERROR 14: Missing element #7008278 referenced by SURF #
