How to pull dynamic viscosity from a face?

RTN3000 · December 7, 2015, 17:17

Writing a UDF in which I need to get viscosity values of the flow for use.

Similar to using F_R(f, t) for the density on that face, or F_T(f,t) for the temperature, is there a macro to pull viscosity?

Was able to figure this one out. There are many more property macros are based on cells than what's stored on the faces, so C_MU_L(c,t) worked for my case.

I just had to get the adjacent cell and thread using:

Code:

c = F_C0(f, t);
t = F_C0_THREAD(f, t);
