A UDF to stop an unsteady run calculation based on the pressure in the fluent

Hello
I have an unsteady 2D simulation in Fluent that needs a UDF to stop an unsteady run.
This UDF should calculate the minimum pressure (according to the pressure versus time diagram) and stop the run when it reaches the minimum pressure.
I think it's not difficult to write the UDF code, but I can't find of a way to import it into Fluent.
If anyone has information about this (writing the UDF code and importing it to Fluent), I would be grateful if you could help me.

(I have attached a picture of the step that needs to be stopped.)
