udf, help plz
 
I have a question,
can we make a boundary condition like pressure inlet, stable by UDF? my boundary pressure increases every time step and I want to make it not to increase and be stable.
thanks a lot for your attention and help

If the pressure at your pressure inlet boundary condition rises although you provided a constant value in the fluent setup, then there is something wrong with the rest of the setup.
A UDF for pressure won't solve this problem.

thank for your help
do you know which setups would make this problem?

Since I know nothing about the setup, I don't know what could cause the error.
