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. |
