UDF for Turbulence Stresses with RANS two-eq model
 
Hi Guys,

I am trying to obtain reynolds stresses with RANS 2 equation models through a UDF. The UDF should calculates such stresses based on bousinessq eddy viscosity approximation for each time step (transient simulation). Then, there shall be time averaging for calculating the mean values of such stresses throughout the entire flow time. Do I need to define user-defined memory?

Any ideas for even similar UDFs?

Cheers, Amr
