  1. Hi Alexandra, Could you be more specific about what you are doing please? Are you doing any electrolyte analysis?
  2. @Martin28 You can use RBE2 elements to connect the laminate with the yellow part.
  3. Hi, One way is to change E value manually and check the results. or Do a size optimization with E as design variable.
  4. Hi @itouila Is it shell elements or solid elements. If you are using OptiStruct user profile, use MAT9ORT which is compatible with solid elements.
  5. Hi Prateek, For topology, You can use OSSmooth to export the geometry from HyperMesh. Here is a tip and trick which explains how to use OSSmooth. http://www.altairuniversity.com/wp-content/uploads/2013/12/1075.pdf For size optimization, you can import the .prop file into HyperMesh along with the parent model to overwrite the new thickness.
  6. Hi Muthu, Few solid elements have almost zero volume which is not allowed. Suggest to remesh those elements and try again.
  7. Hi Boba, Can you contour by selecting the elements of the tube because I see element stresses on tube. I think you are looking at contact forces. Because face comes in contact with inner dia of the tube not the entire Stempel which increases the computation time. I did output contact forces to confirm whether the contact is happening or not. Also I changed the NINC parameter in NLPARM.
  8. This is an intended behavior because they both are not same. Also shell elements does not behave same as solid in bending.
  9. @Roy Duan I think it is not directly possible. Let me check if there is a way to do this using Math functions.
  10. Hi Rohith, Is it possible to share the .mvw and related files?
  11. @denizbilgili Looks like most of the curves are in a plane whose z coordinate is 80.5. But the two curves (representing inner race and outer race) have z coordinate = 80.4993. Adjust the z coordinate of origin of Curve Graphics so that all are in the same plane and then you should be able to run the model.
  12. Hi @Karthic, OptiSrtuct NLGEOM uses RADIOSS in the background ( we call it as bulk 2 block conversion). NLGEOM does not convert SPCF you need to add in .rad files (REACX, REACY, ...), You can use SI unit when having N, mm, sec.
  13. @boba_fett You are right, I was looking at wrong side of the component. Can you try this model? test_04.fem
  14. Hi Mithun, What type of analysis are you planning? If it is just a linear static analysis, you can model using Seam weld>> Adhesive
  15. @boba_fett The dia of Rohr is more than dia of stempel and it is natural that it passed through it.
