interior in Ansys Workbench
 

Hi every one

I have a simple tube with 1m lenght(1 zone). in Ansysworkbench I slice it with a surface in center(two zone). Ansys create connections automatically. but in fluent will disapear interior B.C for choosing central surface. I tried different ways but I could not solve it for six month. this problem is a interior problem or a interface problem.
Your help is greatly appreciated.
Thanks.

I found the solution myself.
first check connection in meshing that be correct between the face of zones.
second for each face of two zones and zones create name selection. this work is useful in fluent for easy creation of interface. as you create interface from two face, interior B.C will be created. but for getting contour you should choose interface.
