Run-time library dependencies

Hey everyone, I’m trying to set up a Docker container, in a Linux like environment, with a TOUGH3 executable in it. When I attempted run the executable, I got a missing library message: .…

Re: Compiling and Running TOUGHREACT v3.32 using Ubuntu/Linux
@Daniel Carbajal, did you compile and build this executable yourself, or are you using the one provided by LBL? Also, how many flow elements and connections does your problem contain?…

Re: Compiling and Running TOUGHREACT v3.32 using Ubuntu/Linux
@Daniel Carbajal, I received your latest message in an e-mail, but I'm failing to see it pop up on the Forum thread here. Could you try re-posting?

Re: Print out of permeability reduction
It's been a little while since I ran ECO2N, so I can't remember the answer to this, but does it look like the absolute permeability changes with solid salt saturation? If so,…

Re: Maximum point for time-dependent injection
It just means you can only enter up to 4 entries per line. To enter 10 entities, you’ll need to use 3 lines (4 on first, 4 on second, 2 on 3rd). Enter the times in the first 3 lines,…

Re: Error running PEST protocol with model generated by Fortran executable
Thanks Stefan! It turns out the issue I had, in addition to what you pointed out, was with the OS and iTOUGH2 executable I had built in our cluster. I tried building it in a common directory for…

Error running PEST protocol with model generated by Fortran executable

Hey everyone, I'm trying to use the iTOUGH2 PEST protocol to calculate coefficients of a constitutive model relating the viscosity of a sodium nitrate brine with mass fraction and temperature.…

Re: Specifying initial conditions for layered reservoir
@Refaat G Hashish There are many ways to do that. I'm sure that toughio can handle it, but you could also do it by hand by smart search and replace features in a text editor,…

Re: Specifying initial conditions for layered reservoir
@Refaat G Hashish Yes you would put a large boundary element at both the top and bottom.

Re: Specifying initial conditions for layered reservoir
@Refaat G Hashish have you considered setting the temperature of the top and bottom boundary elements? For example, if you have 30 10-m thick layers, and you want to keep that gradient,…

Numerical instabilities introduced after printout

I'm running a simulation with intermittent printouts using TOUGH3. I noticed that, after some of those printouts, numerical instabilities are seemingly introduced that stall the remainder of the run.…

Re: TEMPERATURE = 0.000000E+00 OUT OF RANGE IN SAT
Yashesh, it also appears you're trying to run this in parallel. Are you using TOUGH3, by chance?

Re: Phase transitions with tough3-eos7r
Hey everyone, I still have to do a few more checks on this, but I think I may have found the cause of this issue. It has to do with how the primary variables are re-initialized after the evaporation…

Re: Phase transitions with tough3-eos7r
Thanks Chris! For this particular problem, I was able to get it to make better progress by setting WNR=0.98 and also incorporating the MOP2(29) feature for finite window phase transitions,…

Phase transitions with tough3-eos7r

Hey everyone, I wanted to share an issue I've been having lately. I'm attempting to run a simulation with a vaporization front using tough3-eos7r. I've successfully run the problem with eos7,…

Re: TOUGH3; Running time is too long
I have been changing WNR in PARAM.3 to something less than 1 (between 0.95 - 0.99). This induces over-relaxation and will sometimes prevent phase shifts between Newton Raphson iterations from…

Re: Radial mesh
@Antonio Wu, The RZ mesh is meant for axisymmetric models, meaning that at any value of theta the simulation output for a given R and Z coordinate will be the same.…

Re: Convergence failure at production well
@Antonio Wu , I'm sorry for taking so long to respond to you. The printout it's giving is from the intermediate Newton-Raphson (NR) attempts to move the simulation forward during the current time…

Re: Convergence failure at production well
Can you re-run the simulation with MOP(5)=3? This will print out EOS information that may shed some light on your issues.

Re: Reduced time step when water boils
Antonio, It's quite normal. As you might expect, the properties of the water are undergoing significant changes over a short amount of time when a phase shift occurs.…

I agree with @Christine Doughty that you need more gradual spacing, but perhaps it’s worth a shot to limit the size of your time stepping purposefully.…
