INCON format in the *203t ECO2n samples
In the samples for Tough3 ECO2n, there are several cases whose name ends in 203t where the INCON keyword looks strange to me. For each element, there are 6 lines for the values of the primary…

Does TMVOCBio in TOUGH3 have any option for 3-phase hysteresis
Hi all, What I recall is that TMVOC did not have Hysteresis options for three-phase capillary pressure and relative permeabilities (see the link). Seems it is still the case in TMVOCbio (in TOUGH3).…
