Openfoam Pimplefoam k-epsilon RASmodel postprocessing
 

Hi

when I simulate the openfoam k-epsilon model with postprocessing Uprime2mean, I got the 3 variables in my paraview

first one is just U

second one is Umean

and third on is Uprime2mean which is Reynolds stresses

I just wonder the does U(first one) is the instantaneous velocity???
then can I get the fluctuation component U-Umean???

Thank you for in advance

Best Regards
