Shadow face extraction
 

Hi,

I have a model with fluid mesh (tet mesh) with inserted shell layers. I have done the meshing in DEP mesher. I want to have shadow faces for the attached shell surfaces to make it as wall boundary.

Now the mesh is in Nastran format, when I import the mesh in to fluent the shell layer is missing, I am not getting the shadow faces in the fluent. But when I do the meshing In Tgrid, Tgrid preserves all the information and fluent is able to generate the shadow faces.

But I have to use the DEP mesher to get the good quality mesh. Please, find a solution for me
