Re: anisotropic permeability for TOUGH3-EOS7
Dear Cheng-Kuo, I am not sure why your problem (3) is giving such big residuals. But some of the values in the PARAM block are surprising to me. Could you try it again changing NOITE from 4 to 8 (or…

Re: anisotropic permeability for TOUGH3-EOS7
I got a similar error message when trying to use MOP2(20)=1 and putting permeability modifiers in columns 81-110 for a big problem (134,000 elements). I switched to MOP2(20)=0 and putting a…

Re: anisotropic permeability for TOUGH3-EOS7
Dear Cheng-Kuo, Your test problems are similar to the ones I tried. I have not figured out what is wrong, but I have some suspicions. I am going to check with Yoojin Jung, who did the coding.…

Re: How to determine the influence of boundary size
Hi Sawyer, If you want your boundary to be far enough away to encompass a CO2 plume you are injecting, I wrote a little article about that a few years ago ( Doughty, C., (2008).…

Re: How can I simulate the thermal diffusion (Soret effect) ?
Dear Zaki, I checked the documentation for TMVOC (the multi-component version of T2VOC), which can handle methane and n-butane. The Soret effect (mass flow caused by a temperature gradient,…

Re: Problem with two VOC
Dear Ito, I think there are tabs or other special characters in your input file that do not show, but that the code cannot read. Check line 69 (the new line in the PARAM block),…

Re: Problem with two VOC
Hello, I found two errors in your ab.dat file: In the final line of the PARAM block, you are not specifying enough initial conditions for a problem with 4 components plus energy.…
