Problems in boundary layer meshing

February 17, 2006, 15:40

Hi all,

I am using boundary layer in GAMBIT to create a dense mesh near the wall. I am getting following error messeage:

Warn: Mesh sizes on the face channel is is smaller than geometric tolerences. Use larger mesh sizes or larger geometry.

What could be the mistake. I have tried many combinations of boundary layer parameters and also meshing of edges. But same warning.

Thanks

yes I have the same problem in gambit so I make only surface mesh in gambit and export the surface to Tgrid making BL and then 3d mesh...Its very easy to create BLs in tgrid... install Tgrid then we can talk ok?
