  I'm doing my thesis work and I'm trying to simulate a pumo impeller for liquid hydrogen but I have a problem with turbogrid. My impeller has 11 plitter blades for every blade set and turbogrid cant create a topology for the mesh. Can I create a custom topology or how van I fix this problem? Please help

  TurboGrid only supports up to three splitter blades. If there are more than three splitter blades, here is one option:
  - Define the geometry with all splitter blades in BladeGen. Export the Neutral Data File (NDF)
  - In BladeEditor, load the NDF file. Create a StageFluidZone. Suppress the blades.
  - In Ansys Meshing, generate a tet/prism mesh with inflation on the blade passage.
