Hello all,
some days ago I faced a problem regarding periodic boundary conditions in ANSYS Fluent and after it was solved I wanted to share the solution I found.
To be able to have periodic boundary condition in fluent you have to define it somehow in the meshing stage. In Gambit it is pretty straightforward but in ANSYS Meshing it's completely different. You have to insert "match control" on the faces you want to be periodic.
1) If the geometry is linear, for example like a rectangle, you select the 2 faces as high boundary and low boundary. Then, In the "coordinate system" section you must define separate coordinate systems on each face and then do the rest of the meshing.
2) If the geometry is rotational like a cylinder, you do as stated previously, except, instead of coordinate systems you should define an axis of rotation in the "match control" itself.
I hope I've been able to help you and be as clear as possible.
