Create Patch for MRF Wind Turbine Simulation
 

Hello,
I want to create a patch for defining nonRotatingPatches in the MRFProperties file.
I created the mesh with Pointwise but I donìt know how to create the patch. The zone in which I want to create the patch is the one selected (white) in the picture.
I tried with topoSet and createPatch but, since in my faceset there is also the blade I am not getting what I want. Does anyone know how to create it from stl files? Are there other ways to solve this problem?
Thank you!

As mush as i know, in MRF simulation you just need to define MRF zone, then all other patches out of MRF regions are non-rotating.
whats your question exactly? could you please provide a picture
