Periodic B.Condition
 
Hi Everyone ! how are you doing ? hope well. Iam trying to simulate the through compressor blade (in 2D), Using Gambit, I created the mesh around the blade, and when I tried to export to Fluent, it showed me that there is error in Periodic Condition, so , iam asking if there is anyone can help me to solve this problem. thanks in advance

HI

For the periodic bc. you have to link the edges (in 3d the faces) before you mesh them. The mesh has to be exactly the same on both sides if you want to use periodic bc

Re: Periodic B.Condition
 
Try setting the periodic boundaries as two separate bc's, such as two symmetry bc's, in Gambit and then forming the periodic bc in fluent using the text interface as below.

grid/modify-zones/make-periodic

Before forming the periodic bc check that the fluid zone's origin and axis are defined correctly under the boundary conditions panel.

If this does not work, I'll need more info on the error message you're receiving from fluent.

Hope this helps,

Mark
