Hello guys . Does anybody know how to simulate the deformation of the soil caused by fluidflow in both TOUGH and FLAC3D? Thanks

          Unfortunately, it is not as straightforward as it sounds.

          The "easiest" way that does not require access to TOUGH source code is to make FLAC3D call TOUGH at each time step and import the pressure and temperature from TOUGH into FLAC. For two-way coupling (stress-induced porosity/permeability changes), you should update TOUGH input files before calling TOUGH in FLAC3D.

            Floriane Youzan Yes, every units in TOUGH are defined following the International System of Units.

            Floriane Youzan I thought it was obvious that the code was only partially completed. The command to put in subprocess to call TOUGH depends on too many factors such as how your computer is set up, which version and EOS of TOUGH you are using, is it compiled using WSL, Cygwin or you just got the executable file from LBL...

            Keurfon Luu can you please give me some references that can help me write the rest of the code ? 
            thanks

          I guess this reference from Rutqvist gives you a good overview of coupling the two codes.

          Julia

          Floriane Youzan Hello, hope you are doing well! I have found this discussion topic very useful for my research. I am writing on behalf of the GEERG research group from Nazarbayev University.  Currently, we are working on CO2 potential leakage through fault zones using TOUGHFLAC simulation. I am new to this, and for now, I am learning from manuals and other publications on this topic. 

          Could you please provide information/example problems/manuals in this simulation? Thanks

          Floriane Youzan Hello, hope you have solved your problem! Now I am confused about the strain induced by the pore-pressure change. Can you give me some advice? When I import the pore-pressure from TOUGH to FLAC, I can find that the effective stress in FLAC have changed, but no corresponding strain generated, so how can I calculate the corresponding strain? Thanks
