I am looking to get a mesh of a full centrifugal pump. I have already created the inlet and volute meshes. I just need to now create the mesh of the open impeller and rotating domain. A simplified version of the impeller looks like this.
There exists a clearance between a cutter bar acting as stationary wall and the blade tip of around 1mm. You can see the clearance here.
I wanted to use Tetra to create something quite quickly, as this will eventually need to be automatically meshed during a design optimisation routine, and I thought Tetra would be more robust, but it seems like tets with prisms have a lot of problems with the sharp sweep angle and the clearances.
Does anyone have any suggestions about the best method to mesh this geometry?
I can upload the files if you need them.
