  1. Hey guys, I have some meshing problems and hope you guys can give me some tips. 1. Lines on geometry surface. For example, I turned a STL file (surface geometry defined by triangular grid) into STEP file (solid body) and the triangular grids stay on the solid body surface. If I don't toggle (Geometry - quick edit - toggle edge) those surface lines, the 3D mesh (volume tetra) or 2D surface mesh (2D automesh) are gonna follow the those surface lines. If I toggle those surface lines, volume tetra or 2D automesh won't be able to recognize the surface boundary of the geometry. I have an example geometry attached here, "file 1 - coccygeus left". Let me know how would you deal with the surface lines if you don't want your mesh to follow those lines. 2. Geometry defects. Still, STEP file converted from STL file. Sometimes there are defects in the CAD model, like the surface lines are messed up, as shown in the figure below. Volume tetra won't work properly. I cannot 2D automesh either. I attached the STEP file here, "file 2 - pubococcygeus". How would you mesh this file? Would you clean up the geometry first? 3. volume tetra does not work Still, STEP file coverted from STL file. I see no obvious messed up surface lines, but still, the volume tetra or 2D automesh won't work. I attached a file here, "file 3 - obturator". Please let me know how would you mesh this solid body. Thank you! file_3_-_obturator.step file_2_-_pubococcygeus_.step file 1 - coccygeus left.step
  2. Hello all, In Hypermesh, Geom - "surface edit" sub-panel, while using self intersecting surfs selection of "trim with surfs/plane" radio button, it deletes any overlapping surfaces. I want to keep overlapping surfaces while using this trimming method. Does anybody have an idea about how to do that? Note: Changing autocleanup settings doesn't help.
  3. dear all i want to generate a tetramesh for the model i have attached.. but when i enter tetramesh panel these lines are getting highlighted.. and i have removed all the free edges from my geometry.. how to troubleshoot these? side_analysis.hm
  4. Hello I have a question about preparing geometry to mesh. After using midsurface there is small gap between joined profiles. 1) Before meshing I need to extend vertical element to the horizontal one to have yellow lines and to have common edge? 2) If yes, how to do it if my geometry is not perfect and side surfaces of 2 profiles and not in the same plane. How can I perfectly locate 2 surfaces to each other? In my model 1 extended surface hits target surface too far and on another side miss target because of dislocation. Help me please
  5. Hi, I was practicing geometry cleanup on one of the tutorial models (clip_repair.hm) for tutorial HM-2000. I successfully cleaned up most of the free edges except for one.It is a free edge that forms a closed loop (missing surface). I used Geometry > Create > Surfaces > Spline/Filler, but it doesn't work. Any ideas on why it doesnt work? Thanks,
  6. While editing solid component in an geometry cleaned assembly, the components associated with that solid (other solid in contact and extended surfaces) gets automatically converted to solid. Associated other components get merged into single component with the edited solid. Please help!!! NOTE: If association with other components is broken (by trimming solids into parts) than no such problem arises. Any other method without trimming solid. Why does this happen???
