Fluent – Using periodic boundary condition and rotating mesh

Hello everybody


I have a question concerning the periodic symmetry of a rotating mesh in Fluent. This is part of my master thesis.



The model is a stage of a centrifugal compressor. Here, the periodic symmetry should be exploited so the geometry can be divided into 7 sections (51.4 degrees). The compressor wheel is to rotate in the housing and I load a structured mesh.

What option is there to solve the described problem without constantly load a new mesh. What would the alternatives be?



Thanks in advance

Dennis

Have a look in the 2019 documentation for Fluent, and then Tutorial 10. I think that'll answer your question.
