Hello, everyone

I am doing permeability testing in textiles using CFX 10.0. I used TexGen to create unit cell and I also used it for meshing. When I input meshed geometry which is block and yarns inside it and tried to create boundary conditions I got a problem. I cannot separate faces in block so I can create input pressure and output pressure. So I was trying to find another option, maybe to create another surface above my unit cell so I can create boundary conditions there. I still don't know how to do this. If you have any idea, please let me know. I will be very thankful for any reasonable advice.

Kind regards, Elena

Elena,

Could you please elaborate the problem little more?
