Pressure drop using GENER
Dear Tough community,
I'm trying to run a 1D simulation with initial and boundary waters. I'm using GENER to drive the flow. The program runs, but I get a drop in pressure for each step in flowdata.tec. If I run the simulation for longer it crashes. I think the problem is that the pressure gets so low that the water starts to boil.
I don't understand why I get this drop in pressure because my injection and production rates are the same. Can anyone see a solution?
It appears you're making this a non-isothermal simulation and introducing the fluids with zero empathy. If this isn't your intention, I'd suggest making the simulation isothermal, and at least allowing for the presence of a gas phase (even if it never shows up by the conditions of your simulation) by changing your MULTI block to 2 2 2 6.
Glad to hear it. I did notice your permeabilities were kinda high (~1.0E-12), and the volumes are small, so perhaps any small distinctions between injection and production rates would impact the simulation really quickly. This could be why the pressures in all elements (including the producer element!) dropped monotonically.
