Re: Natural State geothermal model calibration using itough2
I stand corrected, 0.0 porosity values in the INCON block are ignored by TOUGH2/iTOUGH2.

Re: Natural State geothermal model calibration using itough2
It also seems that STEINAR has been used for editing at some point.

Re: SAVE file
Are you using TOUGH2 or iTOUGH2? If you use iTOUGH2 you could try to set MOP(13)=1

Re: SAVE file
Do you need the permeability values in the SAVE file? Are the changed from that is in the ROCKS block?

Re: EOS1 with 2nd water. Some issues ...
I changed the initial value of COM2 in the INCON file to 1.0E-10 and it seems to run normally - some issue with solver instability I guess.

Re: iTough2 parallelization by PVM
I'm sure it works for inverse simulations, there is no mechanism for solver parallelization in the standard iTOUGH2. Also the documentions mentions the Levenberg-Marquardt algorithm.…

Re: iTough2 parallelization by PVM
Hello Keshvad If you are using a single multi-core machine, you may want to look at the >>> PARALLEL: option rather than PVM - no need to install PVM. Cheers!

Re: INSTALL OF TOUGH2
Have you tried the it2make script while in cygwin? That "should" work. If not, make sure to delete all .o and .mod files in your directory - there is some confusion between iTOUGH2 and TOUGH2 files.…

You can have them to be a ROCKS type with a very high heat capacity.

Good to know that the issue is solved - too bad that the mcmodel option usually results in longer execution times. Given the number of elements and connections your model has I'm a little bit…

Re: Error Codes?
Could be something as simple as this executable appears to be for EOS3 but your input files for EOS7. And this executable only allows for 99999 elements.

Re: Error Codes?
Can you provide the input/output file or more detailed print out from the error message. Most likely the message error depends on the compiler you have used.

Re: No primary variable data are displayed in output file.
TOUGH2 automatically aborts or stops if there is no change in the primary variables during consecutive 10 time steps - see DX1 and DX2 in your output (3rd figure).…

Re: "EOS CANNOT FIND PARAMETERS AT ELEMENT" error message
I would recommend using gfortran (via MinGW or cygwin on Windows) rather than g95 since I think the g95 project is now semi-dormant. But you can try to add the -r8 option. http://www.g95.org/docs.…

What compiler do you use? Make sure to use the appropriate flags or options to generate a double precision executable.
