Hello !

I'm working on a vertical gaz/liquid separator. I have one inlet for the mixture ( gas+ liquid) and two outlets ( liquid outlet and gas outlet ). I use VOF model.

my BC are mass flow at the inlet and pressure for outlets.

I know the gas outlet's pressure but concerning the liquid outlet i have to set the pressure outlet with udf because it depends of the interface level.

Do you have any suggestions or ideas of a sample UDF code or function to do that ?

you can find a sample of the problem with an attached files.

Thank's
