Refining Mesh
 

Hi Foamers,

i am using the sonicTurbfoam prism case for supersonic flow.
i have already changed the velocity and all but the mesh generated is is some what inaccurat..... i am trying to refine it near prism area to reduce y+....but i am unable to set grading ratio correctly...i am trying to edit it in BolckMesh Directory ....... do you know any other method? can some one help me in this regard.

Thanks
