Can you specify the problem in detail?

hi,

for example, if you want to define two opposite faces F1 and F2 of a cube as periodic, 1. applying meshing schme for the faces of cube. 2. Then link the faces F1 and F2 by using commands in Face mesh panel. 3. Now apply volume meshing schemefor the cube. 4. In define boundary conditions panel, select faces F1 & F2 and define them as periodic.

This is one of easy way to define periodic boundary conditions. you can also define periodic boundary conditions in FLUENT for non conformal meshes.

hope it helps you!

hi i am just doing a mixer analysis and there i used periodic boundary condition as given in tutorial so i have used symmetry boundary conditions it does not work b/c i not very high force second my volume integral is mush higher than expect any suggestion please tell me

hi i am doing problem in 2d and i linked edges of blades face with outer shroud face edges and set interior boundary conditions in gambit but when i import them in fluent it gives error that then cannot be interior.plz help in this regard
