Hello everyone,

I want to perform an unsteady CFD simulation of a variable pitch fan (variable pitch rotor + fixed stator) in order to understand the effect of movement of the rotating fan blade on the fluid flow. Therefore, I am looking for solver+mesher which is capable to handle dynamic mesh (or overset mesh or moving mesh) in a rotating frame of reference. Ideally, I would like to solve only 1 rotor blade + 1 stator blade (instead of all the blades) and each row in their corresponding frame of reference.

I looked into the documentation of FineTurbo and STAR-CCM+ but they do not allow it. Can any one suggest any software which is capable of doing this ?

Any help is appreciated.

Kind Regards
Abhishek VERMA

OpenFOAM v1706 introduced overset mesh functionality. Take a look at here.

Dear Ornax,

Thank you for your message. In the end, I ended up using Star-CCM+'s morphing technology. I tried using overset mesh in Star-CCM+ but since there is wall-wall contact, it resulted in simulation error

However, it is nice to see that OpenFoam has launched Overset meshes.
