Mixing Plane Model

[kuvodich]

Hello, I am trying to simulate an axial fan in a duct, and would like to solve as steady state using mixing planes between the rotating blade region and stationary duct regions. I am trying to follow along with the following example videos

but I do not see the option for "mixing planes..." under mesh models (see attached). Is this option not available anymore in fluent? In the videos above it does not seem they had to define any turbomachinery topology to access the mixing plane option. What am I missing? In one example, they imported two case files. In another, it is one mesh file with two fluid zones, one rotating and one stationary which is what I have. Thanks!

Hi, the Mixing Plane model has moved to the Turbomachinery tab and can be enabled from there. There is a tutorial in the Fluent documentation that describes how to set up such an interface. In this example a No Pitch-Scale is used, but the process for Mixing Plane is the same.
