Hello all,
I am new to fluent and I want to use a UDF for defining the granualar viscosity of the secondary phase in the mixture model : mu= -0.188 + 537.42*Volume fraction. I had written the follwoing UDF. #include "udf.h" DEFINE_PROPERTY(solid_viscosity,cell, thread) { real mu; real vf=C_T(cell,thread); mu=-0.188+537.42*vf; return mu; } This is correct? And how can I use this in my case. Can anyone help? Thanks |
