Dear Friends,

My question is related to the Fish tale* that usually occurs in velocity distribution across a blade profile, as you compute the 2D solution around a blade profile (turbine vane or blade for example). Recommendations I got previsouly were to your CUSP scheme, however I can only use this for H-grid generation in software that I use. Based on experiences, I wish to use OH grid instead and there I can not resolve this tale issue...
Anyone who faced same problem and how did you resolve it, how did you do your mesh refinements to get this effect out of your profile velocity or Mach distribution? My intension is to learn better based on your experiences.. as I am quite new into CFD studies..
please note that I am using a CFD program where I have freedom to use H. OH or O grid only.
