How to write a UDF of Viscous Resistance

lbj007 · October 8, 2020, 11:42

I found this in udf manual,but I don't understand the difference between F_PROFILE and C_PROFILE,in which case need I use F_PROFILE/C_PROFILE?

F_PROFILE defines variable on faces
C_PROFILE defines variables in the centers of finite volumes (cells)

but shouldn't Viscous Resistance be the variable of cells? How could it be on faces?
