[GAMBIT] Question about meshing two triangular face

wanghaojie · November 18, 2013, 17:46

Hi all,
I have a case that have a overhang type of window. There is some angle between the overhang window with vertical direction.
Part of the geometry is like the link below (I have larger volumes outside it to form boundary layer flow). The diagonal plane has a wall-type boundary condition and airflow can go around it. When i mesh this volume and try to project it down stream, gambit always says the face that i'm trying to project to can not project along.
Anyone can give me some advice? Many thanks,

from your picture you have one diagonal split, (and if this diagonal has wall-BC, then airflow cannot go around since the diagonal splits all your volume)
Regarding the mesh, what kind of mesh do you want? (tetra and cooper shouldn't be a problem)
