Re: EOS1 - REDUCE TIME STEP error
Sara, I look at your files. I can only repeat what I said in my previous reply: The production rate is (way too) high for the specified initial conditions.…

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: Inversion of tracer test data
Alfonso, You sure can. Inversions of tracer data (or any other breakthrough curves), however, have their own challenges, specifically if you have a pulse injection.…

Re: Anisotropy in Gslib
Saba, The definitions come straight from the GSLIB User's Guide. I find them confusing as well. I propose you simply generate a field with a given angle and anisotropy factor and visualize it - this…

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
Laura, I understand what it is you wanted to simulate. However, my question is how you actually implemented the well in your model (is it a string of high-permeability elements?…

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
Jaechul, You should have a CONNE block, at least for MESHfracture. Note that in case you use a dual-porosity model, the CONNE block for MESHmatrix2 will be empty (as there are indeed no…

Re: MINC problems in post processing
Dear Mr. Ha, Dividing your MINC file into separate files (one for each continuum) is exactly what minc2mesh.exe does. After running minc2mesh.exe, you should (for a double-porosity or…

Re: MINC problems in post processing
Mr. Ha, I wrote a short program (minc2mesh.exe) for you that splits MINC meshes into separate MESH files (one for each continuum) for subsequent EXT processing on a PC.…
