What's wrong with my UDF?

mhey01 · January 31, 2019, 12:11

Hello,

I'm trying to use this UDF I was provided with for my simulation of blood flow through a stented artery. I don't have a lot of knowledge with UDFs or C programming.

The UDF is for a transient inlet velocity boundary condition, but when I try to interpret it with Fluent, I get an error saying that the function "vel" was not found. The error also says that prototypes must appear outside of the function body.

If anyone has any advice I'd be very grateful.

Thanks

It appears that there is a mistake in the code of your UDF.

I have no psychic powers, so I do not know how your code looks like. So I can not give a better answer.
