Wind Turbine, polyhedral mesh

Nabuchadresar · August 28, 2015, 17:07

I'm trying to simulate a wind turbine. In the region near the turbine my cells have varying sizes. I wanted more uniformity in this region, but I can not do it. Can anyone help me to leave my more uniform mesh?

Well, this mesh is good?

Thanks for you help.

First thing I would do is reduce the surface mesh on your turbine surfaces. Part of the reason that you see that line of fine cells with much large cells behind it is that you have too large of a gap between your large and small surface mesh sizes.

Your prim mesh is constructed from your surface mesh, so basically you need to limit what it can grow to near the turbine by changing the size of the turbine surface mesh.

Another thing you can try after fixing your surface mesh is to customize the prism mesh tet/poly density and tet/poly growth rate parameters.
