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
@Jose Kevin Pauyac Estrada Ask for an output file at time 295s, right before the code stops. Check the temperature and pressure in your model. What is the highest temperature?…

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,…

Re: At KCYC=1, EXCEED GENERATION TIME TABLE AT ELEMENT #####
Hi Eric, Without looking at your input file it is hard to figure out. For example, do you have a TIMES block that has time monotonically increases? How about you try: 1.…

Re: How to create meshes with local grid refinements
I think what you wanted can be accomplished by using AMESH (https://tough.lbl.gov/licensing-download/free-software-download/), then rotate your mesh (it seems you do not need refinement in y…

@Nelson Molina Giraldo Then you will have to use the old trick, copy SAVE to INCON, modify input and re-start a run, you probably should write a script file to do it if the material need to be…

Re: Time-Dependent Material Properties
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

Re: FOFT keyword no printing
Hello Maria, Since you are running iTOUGH2, an alternative would be put those elements in Observation blocks in iTOUGH2 input file and ask for time series of interest for the times you selected.…

Re: creating T2Well .exe from source code
Hello Hannah, Linking T2Well to TOUGH3 may be more than changing the NMAKE file. T2Well source code that is linked to TOUGH2/ECO2N will need to be changed as well.…
