Hi,
I am using a UDF to specify a pressure boundary condition. I want to know if that when I reach a specific pressure, how can I stop using the UDF at that time-step and change the BC.

I use a journal file to give the commands, so in short, if I get that pressure condition, I would like to change the BC from the UDF to a constant using the journal file itself.

Has somebody had any success or experience in this?

I don't know whether the following could be helpful.

Maybe you can use 'If' statements in your UDF to define BC, e.g.

If(pressure_now<pressure_condition)
{}
else
{}
