cfdworks is on a distinguished road
Hello everyone

I am currently working on generating a 3D unstructured mesh for the impeller and diffuser below.

I would first like to generate an octree mesh followed by a delaunay mesh. I would like to seek advise from any experts here on how I should go about setting my mesh sizes, such as scale factor, max. element, min size limit and refinement number etc.

Should I also enable prism for all the walls at part mesh setup?

I tried generating an unstructured mesh with all default settings and I get the following warning message. 'The mesh size appears to be inadequate to represent the geometry. Do you want to run with autosizing?'

Any advise / tips are appreciated. Thanks in advance!
