[Other] Meshing sharp edges

kandelabr · August 9, 2017, 05:20

Hello everyone,

I know this is a very common problem but I haven't found a solution yet.

I have a geometry with some sharp edges that will definitely produce skewed cells.
What can I do to make a good mesh? It's a rather simple pump impeller that's connected to volute with ACMI. I can't change the geometry because that would mean I'm running a case of a different thing...

See the troublesome spots in attachment.

Thanks!

*Ahem*...

Does anyone have any experience with that? How does one mesh an impeller? Do thin and long boundary layer cells help?

If I was meshing this manually (with a tool I do not know yet

), I would just extrude boundary layers until they all met in the middle.
