Hi, Can any body tell me how to specify periodic boundary conditions in ICEM CFD hexa mesh generation.

Thanks in advance by rajani

Yes, this is a bit tricky.

First make sure that you have defined the periodicity in the Mesh Editor (Geometry/Surface/Mesh Params/Model/Define Periodicity) and save your tetin file.

Then inside Hexa you just need to do Blocking/Periodic Nodes and pick two nodes that are periodic.

You can verify that the periodicity is correct by setting the "Periodicity" display on in the options for the Face display.

Thank you very much for the help. Today i will work on it.
