Re: How should the enthalpy be correctly specified when simulating the process of air injection into an aquifer using TOUGH3/EOS3?
Hello Hanking, For your purpose, you have two ways to handle this: 1. You probably want to inject at a constant temperature. When you specify rate, the pressure changes, therefore,…

Re: TOUGH3 output and ext2
@Mathieu Gossez I do not know if my ext would work for TOUGH3 but you can try. OUTPUT_ELEME* is a much better option, which you can output exactly what you want,…

Re: Format of file where pressure changes over time
@Jordon Massey I did not check the format but I see you have "B53 " as an element name, which I suspect checked you had " B53" as element name in the MESH.…

Re: Print out of permeability reduction
@Prince Kumar . I understand you are using TOUGH3. Since TOUGH3 combined features from both TOUGH2 and iTOUGH2, there is a possibility that the trick below from iTOUGH2 works.…

Re: call TOUGH in jupyter notebook and PyTOUGH
I did not look at your output file. But I have a quick guess: you probably either used a wrong input file, or did not delete the MESHA, MESHB in your directory so you are using the wrong MESH.…

Re: Radial heat transfer with MOP(15)=5
Hello Jan, When you select MOP(15)=5, the elements that have a non-zero AHTX will participate in the radial heat transfer calculation. AHTX is the surface area.…

Re: GOFT files only printing for one component (COM1)
Hello Yannick, I see where the bug comes from. The code is printing out based on element name (H1832), not the source name (e.g., GIS01 or I_S01). We will fix it and post the fix.…

Re: T2WELL/ECO2N problem with mass rate
Hello, My suspicion is that due to pressurization, CO2 temperature goes up in the wellbore. If you have formation around the wellbore, the heat will dissipate However, you do not.…

Re: At KCYC=1, EXCEED GENERATION TIME TABLE AT ELEMENT #####
Eric, I do not like seeing "0" in your times block. Can you use "0.001" instead? Now please add back your original GENER block, run again and look at the GENER file it produced,…

I cannot remember if TIMBC only works for primary variables or if you can change properties as well. Check it out in the manual. Yingqi
