  1. Have a look the script "default_component.tcl" within "hm/scripts/browser". Maybe you found some good idea to code.
  2. I don't know where's this script. But by checking .SES file, I found the format is simple. So you can write yourself the script :-)
  3. I make a closed surface mesh firstly and fill with Tetra mesh.
  4. You're the author of your script. So you do whatever you want about your script. Nothing to see with Altair's license here.
  5. It's normal. In big closed volume, you have 327 elems with "aspect" > 20 !!! Again, when you have a bad (see very bad) surface mesh, you risk having error with filling tetra elems.
  6. The first thing to understand: STL can be used directly as FE mesh, but not always. STL is a presentation format, firstly. So surface presentation is based on triangulation as triangulaire mesh. But at the quality level, it's not the same. In your case, your STL model is maybe good enough for surface presentation but not for EF meshing. So you have to do alot of work on this STL before doing 3D mesh on it. Good luck!
  7. You got high stress level, because your structure, your load. Penta elements are also as good as another element type. At your place, I'll check this high stress value to see if it's a physical value? or a numerical value?
  8. Do you're speaking about surface or solid mesh?
