[mesh manipulation] Wall mesh refinement based on y+

Hrushi · July 22, 2010, 04:53

I am able to refine the mesh using refineHexMesh/celllSet utility based on field value like magGradU. It works well.

I had calculated yplus values for my case. Based on that, I need to refine the mesh at the wall. When I give the option of yPlus in cellSetDict, it writes the cellSet c0 having zero cells. This may be becuse all y+ values are reported for boundaryField not the internalField.

So anyone knows how to refine the mesh at the wall region based on yPlus value?

Hi!
Could you explain how did you refine the mesh based on a field value?
That would be really helpful.
Thanks
