  Hi, there is a way to write the time averaged mean data of turbulent viscosity in a UDF? Like I can do with the x velocity with C_STORAGE_R(c,t,SV_U_MEAN)/delta_time_sampled.nnIn particular, I would like to write a UDF to get the spatial derivatives of the Reynolds Stresses - d(uu)/dx, d(uv)/dy, d(uw)/dz - that I write with the Boussinesq approximation.n

  No idea, have a look in the documentation and header files to see what's available. Note, the macro may be model dependent. n

  No there is no Svar for that. I remember there is a way via Custom Field Function and but is it not documented and for that reason not supported.n
