  1. Hello, Trim means that for the contact it will not be considered only a WHOLE face, or a set of whole faces, rather will be used if necessary only a portion of a face, using only the elements which are interested. WHithout the TRIM option, a whole face will be included in the contact, as soon as one element of the face is included.
  2. All functions are listed in Help under UTILITIES.
  3. Hello Darad, Saving geometry (only parasolid) into database has many advantages starting from Altair SimLab 2019.3. We are implementing more and more CAD operations which will be available only on Parasolid mesh imported with "Save database" option. For example, you can use options like REMOVE HOLE and REMOVE DETAILS to defeature the CAD geometry even before meshing. You can use the MOVE tool to drag a CAD face, change a radius or a thickness. You can use BOOLEAN operations to join the cad bodies before meshing (very important feature). You can use "fill hole" to fill a missing CAD face. The disadvantage is that there must be a cad conversion into parasolid, and there is always a small risk that something goes wrong.
  4. After doing the shell mesh of the one big connectedbody, select the mesh body, right-click and choose UNMERGE. You will get the mesh of the original bodies, including the original names.
  5. Hello JJJ, currently the video explains what has been implemented
  6. YOu can also turn on a Python Window in SImLAb from the VIEW menu
  7. If you use the new SL 2019.3, you could try to join directly PARASOLID CAD geometry by creating connected bodies in the boolean panel. It is a very very good way of "joining" parts.
  8. In general, I would strongly recommend to export PARASOLID files from Hypermesh into SimLab. Starting from v14, HM PArasolid-Export has improved a lot and I would surely recommend it as a interface to SimLab, instead of Step. Just make some attention to the Units, sometimes HM will export it scaled x1000 Thanks
  9. Hi, the easiest way to control the RBE2/RBE3 is using ANALYSIS PROPERTY. It doesn't matter if you created it as a RBE2 or as a RBE3: the property will decide for this. if you don't create one, SimLab will do it automatically, based on the initial setting you chose.
  10. Hi, In the meanwhile, Altair HyperView allows it if needed. The panel is Model/Symmetry
  11. You can not fix the rotating center using the mouse. Every time you middle click to rotate, this will select a new rotating center. What you can do if this disturbs you is: - use a 3D space mouse: in this case, the "2D"mouse middle click will fix the rotation center, the 3D mouse will do the rotation or - choose under File|Preference|System a different Mouse setting. FOr example, "Hyperworks 13.0" allows to choose the rotation center and rotate separately, like in Altair HyperMesh.
  12. Hi, SimLab is developing quite quickly, indeed many things are changing from version to version. You can still create a makro and a DOE to implement your own mesh refinement DOE like in the past. Additionally, you can try the new approach we are implementing currently. You need to define a BODY MESH CONTROL on the geometry you want to "refine". We still don't have complete tutorials for this, we plan to add one to the Learning Center .
