Hi all,


Please I am new user of PetraSim and would like to know how to show the gas pressure and liquid pressure versus time for the results. I know how to print specific grid. But, the flof excel file shows only a pressure without specifying the phase. Can you please help with that.



Kind Regards,

Abdelrazik Elfar

For 2 phase models, TOUGH outputs gas pressure.  Liquid pressure can be determined based on the capillary pressure:   Pl = Pg + Pc (Pc is defined negative in TOUGH2).


You will probably need to calculate liquid pressure in Excel and create your plot there.


Best Regards,
