CFD of Vertical Axis Wind Turbine
 

Hi,
I am a beginner in using Fluent.
My objective is to perform cfd analysis of VAWT.
While trying to create interface , i am getting this error "The mesh file exporter does not support overlapping geometry in named selections. Please resolve the issue and try again. You can use the option “Show Geometry in Overlapping Named Selections” (when you right click on the Mesh branch of the tree) to help diagnose the problem."
I have attached geometry file.
Also it is possible to give inlet air velocity and calculate what will be the rpm of wind turbine.
Thanks in advance.
