difference plot: turbulent kinetic energy (URANS) vs. Reynolds Stresses (LES)
Hey,
I have two cases (same mesh/geometry): URANS and LES (WALE) I want to directly compare the turbulent kinetic energy from URANS against the reynolds stresses u'u' (and same for v'v' and w'w') in CFX Post. By using case comparison and the "Difference"-function I can only plot the same variables against each other. Is there a way to compare two different sets of variables in case comparison mode? P.s.: I only look at one timestep. No time averaging of LES data so far. |
maybe write an expression (& turn into a variable) and plot that?

yes I just tried the following expression
Turbulence Kinetic Energy @Case:1 - Statistical Reynolds Stess uu@Case:2 When I try to compile it gives me an error: The following unrecognised names were referenced: Case:1, Case:2, Turbulence Kinetic Energy, Statistical Reynolds Stess uu Do you see any errors in the formulation? |
