Hi. Can anybody tell me how can i plot U+ versus y+. In Tecplot i have some variables like velocity, pressure, shear velocity etc. Is it possible to compute U+ or Tau_w from them? Thanks

U+ = (wall tangential speed)/(shear speed) Y+ = (normal distance from wall)*(shear speed)/(kinematic viscosity)

you mentioned you have velocity and shear velocity, but you still need viscosity. if not given, it can be obtained from Sutherland's law using temperature.
