Re: CO2 mass balance
Ram, I agree that your results do not make sense. However, I'm unable to reproduce them (my runs - using various versions of TOUGH2 - all give the correct mass balance with substantially more gas…

Re: Problem initializing a low permeability EOS7C simulation
Hi Michael, Increase the initial time step size by a factor that is approximately equal to the factor by which you reduced permeability. Stefan

Re: How to use TECPLOT for interpreting T2 OUTPUT
Ichwan, Which TOUGH2 version did you use to create the output file? It is in a non-standard format. Yoojin Jung looked at it and found that if you remove the first two columns in the flow block of…

Re: How to use TECPLOT for interpreting T2 OUTPUT
Hi Ichwan, You need to have a separate file MESH (with blocks ELEME and CONNE) in the working directory where you run EXT. Also, make sure you have set KDATA>=2 in the TOUGH2 input file,…

Re: Error Codes?
Hamish, It seems you're running out of memory during linking. Try to add "-mcmodel=medium" to the compiler options COO in it2make (attach your it2make if you need help doing this).…

Re: Error Codes?
Hamish, Sorry, I don't understand. Your model has about 340,000 elements, and about 1,000,000 connections. So you have to dimension MAXEL and MAXCON accordingly. Stefan

Re: Error Codes?
Hi Hamish, The error message 185 just says that an error in the forward run occurred, which is related to the fact that your major arrays are not properly dimensioned, as you have already found out.…

Re: Anisotropic permeability modifier positions
Hi Julia, This is essentially correct. A few comments: (1) This is a new feature only available for iTOUGH2 7.1, which will be released later this year.…

Re: SAVE as INCON: big issue
Hi Quentin, I don't have much information from your post, so I can only guess what is happening. (1) Check your INCON=SAVE file. I presume it lacks the phase indices, i.e.…

Re: How to simulate bubble flow in non-Newtonian fluids (such as drilling mud)?
Qian, To my knowledge, none of the publicly available TOUGH modules handles non-Newtonian fluids. However, Yu-Shu Wu, now at Colorado School of Mines, developed such a module many years back;…

Re: Problems with ECO2N V. 2.0
Gareth, I don't have an answer, just a few questions: (1) SELEC parameter IE(16) can be set to 1 (an integer, not a real!) to revert to the ECO2N V1.0 solubility model,…

Re: Porosity, Permeability and Capillary Pressure Modification Block by Block
Hi Cahli, Make sure you have an empty line before the CONNE block. A missing empty line is all I can suggest from the information you gave me. Stefan

Re: ECO2N Steady state

Re: How to model a leakage around existing well annulus in TOUGH
