Re: INSTALL OF TOUGH2
Ermad, Please let me know what compiler you have. I have to assume that you are familiar with your Fortran compiler. At which step in the process of compiling and linking TOUGH2 do you run into…

Re: How can I add a free-flow Neumann boundary condition to a boundary?
Not sure I understand. You can fix the saturation of any phase in a boundary element, and that phase will then "freely" flow into the domain according to the driving force and mobility at the…

Re: "Default porosity" definition
Quentin, It depends... I propose you look at the governing equations to see how porosity is used (i.e., in the storage term, but also to calculate phase velocities,…

Re: Atmospheric Boundary Conditions
Anthony, (2) Multiple little points: - The porosity in the atmosphere is essentially 1.0, so that's what is specified. - The laminar boundary layer is actually in the atmosphere, not the rock.…

Re: Atmospheric Boundary Conditions
Antony, Just briefly: (1) The suction is NOT overestimated - low relative humidity indeed constitutes a strong water potential, energy that is used to evaporate water and draw it to the surface.…

Re: Atmospheric Boundary Conditions
Hi Antony, There are several ways to simulate evaporation. The most mechanistic approach is to define an air-mass fraction in the atmosphere that corresponds to the relative humidity value,…

Re: Tough2-MP TMVOC module
This reply only concerns your second question: No, there is no parallel TOUGH2-MP version of EOS7C.

Re: EOS1 - REDUCE TIME STEP error
Sara, I have not run your input files, but the message simply indicates that the total pressure is lowered (due to pumping) below the saturated vapor pressure, thus inducing boiling.…

Re: Anisotropy in Gslib

Re: Axis rotation
Madjid, (1) Changing coordinates won't do a thing! TOUGH2 does not use coordinates at all - they are not needed and not part of the IFD forumlation. (2) You would have to edit the CONNE block and…

Re: Define oil and water production rate for cells
Wendy, For the injection well, use TYPE=COM1 or COM3 to inject water or oil, respectively. For the production well, use TYPE=MASS and the total (negative) production rate (you cannot specify the…

Re: lacking of continuous column of CO2 from the injection point to the caprock in a sandstone reservoir model

Re: How can I add a free-flow Neumann boundary condition to a boundary?
Mamun, Assuming you want that fluid can flow in/out from/to the top boundary (atmosphere?), you have to specify a Dirichlet boundary condition there. Dirichlet boundary conditions are specified by…

Re: lacking of continuous column of CO2 from the injection point to the caprock in a sandstone reservoir model
Laura, Can you describe you how simulated the well itself (if flow within the well rather than within the formation is your concern; I'm not clear)? Stefan

Re: Recompiling EOS1 for using LUBAND
Tony, You would have to increase MNEL or MNCON or MNEQ dramatically until NRWORK = 1000+(MNEL+2*MNCON)*MNEQ*MNEQ+38*MNEL*MNEQ exceeds the number indicated in the error message you find in output…

Re: MINC problems in post processing
