  1. Please try the latest 2019.2.1 release. We fixed a bug related to FRF.
  2. Hi Amir, Currently, only surface stresses can be plotted. Internal stresses are not available at this point. Thanks, Girish
  3. Hi Mateusz, Can you confirm if you are using 2019.2 version of SimSolid?
  4. FRF response is normalized to the input. If you are using modal frf, eigenvectors are normalized to mass by default. But that can be changed in EIGRL card.
  5. Hi Vaupel, If automatic re-meshing doesn't work, you could simply import the .grid file. Fix all the failed elements and restart optimization. Girish
  6. Hi Alexander, Check your DTPG card, its missing bead params. Please add them and re-run. Girish
  7. Adrien, OptiStruct does not yet support PCOMP for large displacement analysis. The only alternative is to run it using RADIOSS for now. Girish
  8. If i understand your question correctly, you are doing shape optimization and would like to see the optimized shape. You could use hyperview to load the *_des.h3d file to view shape change. you can also use OSSMOOTH in hypermesh to create a geometry file/ fem file for re-analysis. For FE re-analysis, you could also simply import the *.grid file into HM.
  9. which version of OS are you using? Please use the latest version to run nonlinear implicit analysis, Also use ANALYSIS= NLSTAT and define NLPARM. OS doesn't support NLGEOM or IMPDYN anymore. Check below section in user's guide for more details: http://www.altairhyperworks.com/hwhelp/Altair/hw14.0/help/hwsolvers/hwsolvers.htm?nonlinear_quasistatic_analysis.htm
  10. OS doesn't support axisymmetric elements for nonlinear analysis yet. Also CTRIAX6 doesn't need a property card. Material ID can directly be assigned to the element.
  11. Hi Meera, As the error mentioned, please check for any RBM. Make sure you constrained all degrees of freedom.
  12. Hi, try connecting the web and the lug using CGAPG elements. You can force interference fit by assigning a negative initial gap opening on pgap. Finally run an NLSTAT analysis.
  13. Try PLOADX1 instead of PLOAD. PLOADX1 is used to apply pressure load on axisymmetric element.
  14. Hi Alessio, You can use FATEVNT/FATSEQ to do that. Below is a tutorial. http://www.altairhyperworks.com/hwhelp/Altair/hw14.0/help/hwsolvers/hwsolvers.htm?rd2070.htm Girish
  15. Hi Alexander, Look at your linear static results and make sure you see some displacements, if not, check your load step and make sure you assigned the loads correctly. Girish
