Maximum MCYC
Hi. Although I set MCYC (maximum number of time steps) to more than 1000, TOUGH2 calculation stops at KCYC=1000. Is maximum value of MCYC 1000 ? (This is not described in TOUGH2 manual...…

Is there a limit of injection rate that an element can accept?
Hi, I am running a 2-D planar, unidirectional flow with injection and production at both ends (actually, simulating an aquifer). But I found if I increase the injection rate more than a certain…

Cells with time-dependent concentration?
Hi, I found that time-dependant boundary conditions in flow are possible in TOUGH2 by using FOFT and GOFT blocks, but is it also possible to have a time-dependent concentration at certain element?…

For a same drainage process, why ECO2N with hysteresis modeling and ECO2N without hysteresis modeling have very different results?
I studied the reservoir response to different injection processes. To just test the simulators' capability, I used TOUGH2-ECO2N with the hysteretic capillary pressure and relative permeability…
