Natural State geothermal model calibration using itough2

Hello everyone. I have been modelling the natural state of a geothermal field (which shows excellent convection) using TOUGH2. I have achieve almost perfect fits for a section of the field,…

Run the iTOUGH2 with command line

Hello, I'm student, and a beginner. Now I'm doing a research about multi phase flow analysis. I try to learn about iTOUGH2 with eos3 but I have problem to running it (like the image attached ),…

ERROR: STOP ITOUGH2 : Signal 1 recevied.

Hello everyone, i'm a student, and i'm working on changing the primary variable in iTOUGH2, after some changing in file EOSX and T2F.F and IT2MAIN.F , i compile my executable and when i want to test…

Cannot open file /parallel.info

Hi I am trying to use Parallel option for parallel execution but I am getting error that it cannot open /parallel.info in the itough2 output along mkdir: missing operand.…

Read/write file access w/PEST protocol

I am attempting to use the iTOUGH2 PEST protocol using a bash script as my forward-model executable. This script includes multiple calls of a TOUGHREACT simulation with file manipulation in between…

Error Codes?

Long story short I'm trying to run a very large forward model in iTOUGH2 and have probably narrowed down my problem to having not compiled an appropriate version with enough elements/connection in…

compiling Gslib in cluster

Dear Stefan, I am trying to compile EOS7C-Gslib. It works well on my PC where I used Visual studio. But I can't manage to do the same thing on cluster. I got this linking error: it2main.…

iTough2 parallelization by PVM

Hello, I appreciate a response on some aspects of PVM parallelization, in case you have some experiences with it. Is it possible to do the parallelization on a single machine with extended number of…

iTOUGH2 work with EOS7C

Hello, I am new to iTOUGH2 and wanted to estimate parameters in a model with EOS7C module. I learned from the iTOUGH2 users guide that the maximum number of primary variables (MAXPV) is 4.…

Calibrate rock properties of each element using PEST ?

Hello, I am interested in updating the permeability of each element of a TOUGH2 simulation using PEST, since I aim to calibrate it with geophysical observations.…

Parameter estimates from multiple simulations?

Is it possible, through TOUGH2 or iTOUGH2, to perform parameter estimations based on multiple simulations that are coupled to one another? I know that for a forward simulation you can establish…

Inactive elements

Can iTOUGH2 attempt to estimate a generation rate from an inactive element? This element would define either a Dirichlet or a time-dependent boundary. I'll also have observations on the flow rate…

Outputting total flow rates from the FORWARD option

I'm having difficulty getting iTOUGH2 running a forward simulation to output total flow rates across a defined connection using eco2n. The only way I've been able, thus far,…

iTOUGH2 forward model problem with EOS7C

Hi Stefan, I am testing my model with iTOUGH2 (EOS7C) forward model before I conduct sensitivity analysis. During the iTOUGH2 run, it suddenly stopped showing a message "run-time error M6203: MATH".…

TOUGHIO CO2 Leakage Along a Fault

TOUGHIO CO2 Leakage Along a Fault Generate MESH and INCON files In the second step, I showed that there was a problem with my index, but I checked the files and there was no problem according to the…

What is the expected format for the Grid Search input file?

When I tried to do a Grid Search with 4 parameters I got the message: ***** ERROR ***** * Evaluation of objective function currently only for a maximum of 3 active parameters!…

Can't read MESH properly

Hi everyone, I am facing the problem when running iTOUGH2. The program can't read mesh (minimum X-Y coordinate) properly based on the TOUGH2 model that I exported from Petrasim software.…

Best Fortran Compiler and OS for iTOUGH2

I just received the files for installing iTOUGH2. I have not used the software before and I am new to working with Fortran. I am currently using a Windows operating system and I am wondering what…

iTough2_ECO2M

Hello, I`m struggling with the ECO2M sample 4(*rwaf*) and hope somebody has an suggestion for me. I tried to use the TOUGH3 exe, but the simulation always stops in between and its not running up to…

iTOUGH2 version 7.1

Hi, I was trying to run an example with iTOUGH2 (ver 7.1) - T2VOC for sensitivity analysis, but got an error message (screenshot attached). There was no problem when I tried with same input files…

Anisotropy in Gslib

Hi, I'm using iTough2 and am trying to create a heterogeneous field using gslib. I could not actualy figure it out what is the definition of the ang2 and how to define the anisotropy ratios.…
