Ca Ma,

 

Would it work for you to add a cell with a very large volume to the model and assign it a lower pressure, so that flluid will flow into the cell?

 

If you think this would work, you should take a look at the option to add Extra Cells (which are non-geometric cells) to a model.  This is discussed in the PetraSim Manual.

 

Best Regards,
Alison
