UDF for shear stress at wall in laminar flow

February 4, 2003, 12:04

I came to know that we can use the macro "F_STORAGE_R_N3V" to get the shear force at channel wall.

I used this macro in "DEFINE_PROFILE" macro. Now the code compiles all right, but it give error when I start iteration in Fluent. The error is like "Invalid argument. Not a number".

Does anybody know how to use this macro?

You should paste the code here.
