Element Numbering
I am wondering what convention is used for the alphanumeric (described online as AAAII?) element numbering. For instance: cell #1 = 001, cell #1000 = A01, but I'm not able to figure out the pattern.…

Convergence issue with 1D model for both PFLOTRAN and TOUGH2
I thought the developers of TOUGH2 maybe interested in this problem as well. I'm using EOS3 to solve the two phase problem. The left end of this model is atmospheric open air boundary condition at 0.…

perm. factor
dear all, I want to ask the "perm. factor" in "set cell data", (ex: I want the domain area's K field mean=1E-13 and standard deviation=1E-14) Does it means that I can use Excel to generate a random…

Disappearing gas phase during simulation of CO2 injection
Dear all, I am trying to simulate an injection of CO2 into a brine saturated aquifer with Toughreact 1.2 and ECO2N EOS module (1D, radial). Everything works fine until the gas saturation Sg in the…

Is there a possibility to extent the TOUGH2 pressure range?
Hello everyone, I am using TOUGH2 to simulate two phase flow in deep subsurface waste repositories. The pressures in the systems can reach quite high values due to gas production and high…

Dual porosity flow crash
Hello, I'm trying to set up a EGS simulation where 120 °C water is injected into a 270 °C reservoir. The aim is to get the system up and running with TOUGHREACT but since those simulations keep on…
