Gambit: mesh size to small???
 
Hi,

I am trying to mesh a komplex geometry and get following error for a lot of edges:

"WARN: Exact projection failed for node on edge xx near vertex xx. mesh size may need to be enlarged for this virtual edge if mesh is not acceptable"

I don't have any virtual edges in the geometry. And when I use coarser mesh, the meshing failed as well (mesh size to large in the area of small gaps). I mesh 3D with ted/Hybrid

Anny suggestions??? How can I display, which edges or faces are not succsessfully meshed?

Ralf

I think I have faced this problem once and this may be solved by adjusting the tolerence to a lower limit in the program defaults. It is set to 1e-3 and you can reduce to 1e-5 or 1e-6 to eliminate the problem you are facing. Then try to re-mesh with a finer grid.
