Hi all

To mesh a triangular face,I mesh the edges first to get the vertex distribution I want and then I do the surface meshing.

The surfacic mesh I get doesn't exactly match the surface of the CAD model face (1 edge isn't exactly located on the boundary edge of the CAD face...), so I assume that my CAD model would be altered with such a mesh.

Any advice?

Well, every time you discretize a continuum domain you accept a certain error in the modeling (think of a continuous curve approximated by little segments)...the mesh should be finer not only when particular flow situation are expected (free surfaces, for examples, or shock waves), but obviously also where the domain is geometrically complex.

Edi.

we agree on that, for sure!

I've encountered the pb on a straight line, though... The thing is, I've given cell size constraints, so it seems to me that Gambit can't satisfy all my preferences. But I'd rather like my mesh to follow the CAD model instead of the size setup.

what do you think?
