Re: van Genuchten - Mualem model
Sorry for the late reply, for some reason the Forum did not ping me with your new message. The rel perm and Pcap dependence on lambda can be unintuitive,…

Re: van Genuchten - Mualem model
Hi Nick, Sl is liquid saturation (the fraction of the pore space containing liquid phase). Usually "liquid" means aqueous, but not always, it depends on which equation of state (EOS) you are using.…

Re: I want to install TOUGH3
What kinds of rock mineral analysis do you want to do? TOUGH3 models fluid and heat flow through geologic media, which I do not think of as rock mineral analysis.…

Re: T2Well (Error message)
@Refaat G Hashish Make sure your actual number of elements is no larger than 22000 and your actual number of connections is no larger than 61300. That is the only requirement on MNEL and MNCON (The…

Re: EOS7C WARNING. H2O MASS FRACTION IN THE GAS WAS LESS THAN ZERO IN 1 GRID BLOCKS
Here are a few things to check: Does your grid resolution change too suddenly? I try to make coarser grid blocks no more than 1.5 times the size of adjacent finer grid blocks.…

Re: An error running the "CO2 leakage along a fault" example in toughio tutorial
Please start by reviewing your INFILE, to make sure it does not contain anything unexpected. If it looks good, you can post it here and I will take a look at it.

Re: EOS7C WARNING. H2O MASS FRACTION IN THE GAS WAS LESS THAN ZERO IN 1 GRID BLOCKS
In the past, I have had better success using EOS7C when I specify a very small amount of all components as initial conditions. I use something like 1e-10 for mass fractions,…

Re: Relative permeability curves in tough2
If none of the existing relative permeability options in TOUGH2 provide Krl and Krg that you like, then you will have to create your own. You could take the Krl function from one IRP option and the…

Re: Gridblocks to represent sink and source
There are a few problems with your GENER file: 1. A blank line means you are all finished reading GENER, so move the one you have now near the top of the file to the end. 2.…

Re: Gridblocks to represent sink and source
Dear Mahmud, At first I thought that the entries in the GENER block in your input file were just in the wrong columns. Here is what I thought it should look like: GENER A2R00Inj01 144 76 1 COM1 2.…

Re: Gridblocks to represent sink and source
I think you want one well to be constant flow rate (an injection well) and the other well to be constant pressure (a production well), is that right? One possibility is to specify one mass source in…

Re: Relative permeability curves in tough2
