[TGrid] Blade Edge Mesh Improvement

Torque_Converter · November 8, 2012, 15:05

I have successfully reduced the yplus values all over to near 1. But just at the blade edges, in a very narrow band, I have yplus values over 500. I don't see a way to target and refine these. I'm sure there must be. Does anyone know how to accomplish this?

Would you like to show us some pics of overall geometry, mesh and the problem area?

It's a bit tricky since it is in-development company property. It is a torque converter, and there is a limited amount of space between the turbine leading edge and the start of that turbine domain. The turbulence generated there is large at it is a small but blunt edge. Turbogrid also does seem to provide any control for that specific area.
