hello experts
I am beginer in ansys fluent

I am working on pulse blood flow in an artery. my boundry conditions are

parabolic velocity in inlet and parabolic pressure in outlet.

when I want to interpret my udfs for velocity and pressure, I can not put both

of them simultaneously and fluent considere my last imput file.

now I want to know how can I put udf inlet velocity and udf outlet pressure in

fluent simultaneously؟

best regards

Hello Ramin,
when you want to compile udfs, it is possible to compile your c files seperately,
but in the case of interpreting you can interpret just 1 c file!, so write all of your udfs in 1 c file and then interpret your c file.

Fluent always has the udf.h. You don't need to add it to your lib/folder.

Just add the #include udf.h
in your code.
