I was wondering the mesh geometry quality requirement for the tel2d or tel3d models:
- is it required that all triangles in the mesh are Delaunay? Or is it OK if some are not?
- for the triangles along the physical boundaries, is it required that all triangle circumcentres are inside the domain (especially if finite volume method is chosen)?

Could anyone add your inputs? Thanks

Hello

No there is no requirement for the Delaunay Criterion. This latter is recommanded but not necessary.
Also no need for triangle circumcentres to be inside the domaine, but also it is recommanded since it makes easier the prescription of boundary conditions especially for finite volumes.

with my kind regards
