Hi,

I am modelling hydrodynamics in a stirred tank vessel using the Reynolds Stress Model. I notice that the Reynolds Stresses are given for the cartesian co-ordinate system (x, y, z) i.e.,  UU, VV, WW, UV, VW, UW. Is there any way to obtain the Reynolds Stresses for the cylindrical co-ordinate system (r, t, z), i.e., Vr*Vr, Vt*Vt, Vz*Vz, Vr*Vt, Vt*Vz, Vr*Vz>

Hello,

Since Fluent directly solves for Reynolds stresses in cartesian coordinates, the results will be in cartesian itself (as of now). You need to use UDF or Custom Field Functions to convert the results from cartesian to cylindrical.
