This tutorial demonstrates how you can use the full Hex-dominant Automatic operation to create a mesh which supports the simulation of rotating systems and set up an incompressible flow simulation in centrifugal pumps.
Firstly, the geometry needs to be ‘CFD ready’
The solid volumes should be non-overlapping and should all be touching each other. More specific preparation details are explained here: Cad Preparation.
Basic recommended geometry checks:
Refinement for Blade surfaces
The Simulation Control settings define the general controls over the simulation. The following controls should be applied:
