Re: How to calculate what portion of a constituent adsorbs.
@Eric Sonnenthal or @Nic, can either of you guys help us get to the bottom of this? We're struggling more than we should trying to figure out how to quantify the mass of a sorbed substance,…

Re: How to create the following grid structure
@Refaat G Hashish, no it’s not really designed to do that. It will just turn a selection of elements (based on their coordinates) into a single element.

Re: How to create the following grid structure
@Refaat, TOUGH3 can handle grids like this, but they cannot be created by MESHMAKER. There is a utility that can create a boundary element similar to the arrangement you're showing here (AddBound:…

Re: How to create meshes with local grid refinements
@Alejandro, MESHMAKER won't be able to build the grids you're looking for, but it can be done using other pre-processors. The tricky part is the requirement that the connections remain orthogonal.…

CHEMP block for diesel and gasoline?

Hello, does anyone know where I can get access to a CHEMP block for diesel fuel and gasoline? Preferably, reference documents justifying the parameterization would also be helpful,…

Re: 3D Visualization Software
@Keurfon Luu's toughio application has a pretty excellent exporter to create vtk's, which I've used and imported directly into ParaView. You can find more information about it here.

Re: Infinite Acting Aquifer
@Erik W, you've basically got it right. You won't necessarily need to adjust the dimensions of the additional cells you include, although that would work.…

Re: Infinite Acting Aquifer
Hey Erik! What you'll need to do is connect additional elements at the lateral extents of your model elements having "infinite" (typically 1.0E+50) volumes. The conditions (i.e.…

Re: Pressure drop using GENER
And shoutout to @Stefan Finsterle, who pointed out a typo I wrote in my first response to this thread where I suggested the fluids were introduced with zero empathy (instead of enthalpy).…

Re: Pressure drop using GENER
Glad to hear it. I did notice your permeabilities were kinda high (~1.0E-12), and the volumes are small, so perhaps any small distinctions between injection and production rates would impact the…

Re: Pressure drop using GENER
I'd also suggest including initial conditions in record PARAM.4. These will get overwritten by what you include in INCON, but it's a good practice to put a default setting in there in case you miss…

Re: Pressure drop using GENER
@Eivind, the enthalpy will not matter if you run with an isothermal simulation, but it's good to keep in there anyway. I also forgot you'll need to change the TYPE from "WATE" to "MASS" on the…

Re: Pressure drop using GENER
@Eivind, I think I was mistaken. You're running EOS1, I presume? Try 1 2 2 6 in the MULTI block.

Re: Pressure drop using GENER
Eivind, It appears you're making this a non-isothermal simulation and introducing the fluids with zero empathy. If this isn't your intention, I'd suggest making the simulation isothermal,…

Re: Parallel Output in TOUGH-3
For what it's worth, I've seen this happen before as well, both with the ELEME and CONNE output files. They also appear to print to file out of order at times.

Values <1.0E-100 included in SAVE file with improper formatting.

When running with tough3-eos3, we noticed that there were some values for air mass fraction (X2) that were below 1.0E-100, but the "E" was not included.…

Using TOUGHREACT with outside flow data

So I think the answer to this is "no", but is there a way to run TOUGHREACT using fixed velocity fields provided by an EOS module from another TOUGH code, like TOUGH3?…
