Re: Natural State geothermal model calibration using itough2
@Melissa De Freitas Hi Melissa, if you are willing to use GMS for preparing and populating the input grid to tough2 or tough3 and display the output I have written two simple codes to do this and I…

Re: Natural State geothermal model calibration using itough2
I, my self, use GMS form Aquaveo both for pre- and post-processing. It is actually very useful for producing original state of geothermal fields. This is the way I do it.…

Re: Creating an angled domain
Sulav, to create such a grid, there are a number of ways to do it, but usually you need a software to help you in this. One of the possible softwares is "wingrider" or GMS or LeapFrog (perhaps also…

Re: 9.4 Problem No.4- Five-spot Geothermal Production/Injection(EOS2)
Nathan, I see a number of things that can perhaps create problems. In the PARAM block you have defined the primary variables for EOS2 as: 150. 0.001 4.…

Re: 9.4 Problem No.4- Five-spot Geothermal Production/Injection(EOS2)
@Nathan B. Nathan, can you compare your Input file to that of problem 4? What do you find different? Can you run correctly the exact problem 4?

Re: Post and Pre-Processing free codes for TOUGH2
Could you please send me an output from the tough+ model? I just want to check how different is the TOUGH+ output from the TOUGH2 one. What EOS are you using with TOUGH+ I am very exited in trying…

Re: Post and Pre-Processing free codes for TOUGH2
In case you can or want to use GMS as a pre and post processor for TOUGH2, I can provide free copies of the software that I wrote to you.

Re: Pre- & Post- processors - What are their Pros and Cons?
Dear Ella, In the past for similar problems I have used GMS (Groundwater Modeling System) from Aquaveo. GMS is not free and has very powerful geologic and conceptual modeling tools for pre- and…

Re: permeable faults modelling
If your fault is linear and does not bend too much, an easy way to go around this problem is to rotate your rectangular grid acting on the BETAX variable of the CONNE block so that gravity becomes…

Re: Using the GMS for TOUGH2 visualization
Hi Sarah, TT2M works with a GMS grid. It converts the TOUGH2 node data to a “3D scatter point” file that can be imported into GMS. Then for visualization you need to interpolate this 3D scatter…

Do you need to make a vertical fault with real geology in it?

If you need to add a vertical fault with real fault geology, that is a fault plain with material that changes from place to place, you may use the simple attached procedure to modify your GMS…

Re: TMT2: GMS file format? Amount of cells in y?
Christoph, I know for sure that each Modflow pre- and post-processor have slightly different file format. The differences can arise because a number of tricks are used to reduce file size.…

Re: Well Connection
As an alternative, that worked for me, you may also work directly on the TOUGH2 files (it may appear difficult at first, but the results overwhelm by far the initial discourage you may experience)…

Re: Do you need a pre- and post-processor for tough2? Try GMS.
Hi Elena, To use GMS as a pre- and post-processor for tough2 you have to create a geologic model with GMS. Then you have to map this model on a rectangular Modflow grid (each layer of the grid,…
