I am new to CFD. I have created the CAD model of savonius turbine (link given above). I want help with mesh creation, what should i do for (pick volumes, pick surface)for mesh creation. (external flow for Savonius wind turbine), simulation designer for various properties like velocity, force, average area scalar transport etc. Can some one create a mesh for this model and do a simple simulation, which i could keep as reference, confused with all the menu, selections.
