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.

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؟

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.

Thank you so much

can I write simple C code definning pressure function without udf.h and use it in fluid solution as a boundary condition ???

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.
