Re: Porosity, Permeability and Capillary Pressure Modification Block by Block
Suhendi, You will find out immediately once you start implementing it (or reading the manual!). You will see that in the standard version of TOUGH2, no input is read in Columns 81-90,…

Re: Turbulence in TOUGH2
Hamish, TOUGH2 is based on a multi-phase version of Darcy's law, which assumes laminar flow. However, both TOUGH+ and iTOUGH2 have some non-Darcy flow capabilities based on the Forchheimer equation…

Re: Recompiling EOS1 for using LUBAND
Mamun, I do not recommend to run a 62,000-element (probably a 124,000- or 186,000-equation) model using a direct solver such a LUBAND. Did you try one of the iterative solvers now that you know how…

Re: Mass out problem of Sources/Sinks about drawdown
Hi Ching Huang, There is no such limit. As always, I have to ask what you mean by "it can't run". What is the error message? I have a few thoughts on what may have gone wrong,…

Re: Does the thickness in y-direction matters when using XYZ to generate X-Z mesh?
Shaoxing, Fundamentally, the thickness in Y direction has no impact whatsoever on the simulation results in a 2D model, as long as the injection rate (assuming you inject at a given rate using block…
