Re: Making input file
Madjid, Consider using TOUGH2's MESHMAKER (see Appendix F of the manual) to generate a rectangular XYZ mesh as a starting point. Then use program AddBound or DeleteElements to cut out your trapecoid…

Re: Suggestion in change the GENER
You can simply restart a run (using SAVE - INCON, etc.), and at that point remove and/or insert appropriate GENER blocks. That works, but is tedious if you have many temporal changes.…

Re: Time stepping in dry-out zones
Ravid, No general guidelines; depends, among other things, on what you do with the relative permeability curve (hope you saw the note for CP(2) under ICP=7 in the TOUGH2 manual),…

Re: Can T2VOC simulate different grid increment ?
Nor, The first message indicates that the primary variables are out of bounds during the Newton-Raphson iterations. The second message comes from the solver (are you trying to use the direct solver…

Re: Time stepping in dry-out zones
Dear Ravid, Unfortunately, this reply is not going to resolve your issue. I just want to take the opportunity to explain why this kind of problems are difficult to resolve in a TOUGH User Forum post.…

Re: MINC to simulate dual-porosity reservoir, with some fractures are open, some are closed.
Jing, Just read about the ELEME block in the TOUGH2 manual. The value after volume is the surface area for semianalytical heat exchange (you probably won't need it),…

Re: MINC to simulate dual-porosity reservoir, with some fractures are open, some are closed.
Jing, After you MINCed a primary mesh, you get a secondary mesh (on file MINC) that contains (at least) two elements at each coordinate location: one for the fractures,…

Re: How to switch between injection well to production well (time dependent)
Flybear! Yes, use the time dependent generation/injection rate in GENER to switch from injection to production. Use two sink/sources in the same element,…

Re: Can T2VOC simulate different grid increment ?

Re: Can T2VOC simulate different grid increment ?
Hi Nor, Well, it's (almost) the correct format, but most likely not what you intended (I'm just guessing here). Please read the manual under MESHMAKER,…

Re: iTOUGH2-GSLIB grid definition and mapping
Hi Kue, As you know, the permeability field generated by GSLIB on a regular grid is on the file you specified in the GSLIB block. The one that is mapped onto the TOUGH2 grid can be found in several…

Re: Can T2VOC simulate different grid increment ?
Short answer: "yes, it can!". I cannot say more, as it is unclear what "does not run as usual" means. Make sure you design your irregular or unstructured grid appropriately.

Re: Using MINC to represent groundwater flow in fractured porous media
Neil, First, the MINC approach is more general, i.e., not limited to uniform fracture spacings (e.g., there is a proximity function for randomly spaced and randomly oriented fractures).…

Re: Steam injection about TMVOC

Re: System of equations for EOS4
In TOUGH, vapor mass fraction is not defined as Mv/Ma, but as Mv/Mg=Mv/(Ma+Mv)=X^v_g, where Mk indicates mass of component k (not "mass fraction") in the gas phase. Therefore: X^v_g=(18.…
