- Thanks for a very informative post. Here's another question. What are
- the latest in Mesh Generation techniques?
-
- The last time I dabbed in FEM, the finite-octree (w Delaunay triangulation)
- appeared the most promising but there were some concerns about robustness.
- I know that companies like PDA engineering (developers of PATRAN) were
- looking at "paving". What is the current status of these two techniques,
- and are there any new ones out there (AI approaches etc.)?
