Turbogrid Shroud-Hub Mesh Measure Limits. Turbine
 

Hello. Im working with a Francis Turbine. Im making the mesh to the distributor. Im meshing with turbogrid.

I want to know some advices of the mesh quality for the Stay vanes mesh and. the guide vane mesh and the blade (runner) mesh.

Minimun Face angle? Maximun face angle? Maximun element volumen ratio? Maximun edge lenght ratio?

What advice you guys give me, to have a good mesh? those parameters depend on what? I would like to have a reference for those values.

Thanks Santiago.
