Re: How to account for evaporation Sw initial < Swir
Hi Carla, If you represent infiltration as a mass source of water, then Sw will increase at your infiltration locations and eventually Sw > Swir and liquid will be mobile.…

Re: How does one track internal progress while the solver is iterating?
I am able to edit the output file while the code is running in an Ubuntu window. I use the text editor vi. I get a warning message when the file is updated,…

Re: Non-isothermal solution crashes
Yannick, According to the output file you attached, the code completes one step and then crashes while printing output. Near the top of the output file are some error messages regarding the input…

Re: CANNOT FIND PARAMETERS AT ELEMENT *00001*
I just thought of one more thing. Your first element name is 00000. This makes me kind of nervous, since TOUGH can read zeros as blanks and vice versa.…

Re: CANNOT FIND PARAMETERS AT ELEMENT *00001*
I think there is an inconsistency in your input file. I haven't used ECO2M for a while, and never in TOUGH3, but I found the following in the User's Guide.…

Re: CANNOT FIND PARAMETERS AT ELEMENT *00001*
I notice in your output file that files MESHA and MESHB exist. This should only occur when you have not changed your ELEME and CONNE blocks (or MESH file) from the previous time you ran TOUGH3.…

Re: injecting VOC mass through virtual cells
Dear Alireza, Your input file does not match what your message says. You do not have any mass sources- these would be specified in the GENER block and yours is empty.…

Re: T2Well-ECO2N
TOGA does handle three-phase flow, and when I asked Lehua about the possibility of using it for CO2 in liquid, gaseous, and supercritical phases (like ECO2M), he said that formally it should work,…

Re: Not to achineve the end time and no error

Re: T2Well-ECO2N
Dear Godarzi, To help you decide whether you need ECO2M versus ECO2N, below is the phase diagram of CO2. If your problem will not cross the saturation line (shown in black) or get near the critical…

Re: Not to achineve the end time and no error
The code seems to be pretty unhappy, reducing time step frequently. To know more about what is happening, I recommend setting MOP(1)=1 (to see iteration information), MOP(5)=3 (to see phase changes),…

Re: How to consider the evaporation effect of water affected by temperature in tough2
Dear Sue, I am hesitant to send you the source code for the subroutine that calculates saturation pressure as a function of temperature in TOUGH3, because it is not designed to be used in…

Re: How to output viscosity in the output results
Use the OUTPU option in TOUGH3, described in the TOUGH3 User's Guide starting on page 83. See Table 8 for a description of all variables that can be output for each grid block.

Re: How to consider the evaporation effect of water affected by temperature in tough2
All versions of TOUGH can simulate evaporation. The instructions you show give three options for how to specify a evaporation at the ground surface. More details on this topic may be found in the…

Re: Infiltration into dry soil

Re: Coupled reservoir-wellbore model initialization (using T2Well)
I am generally familiar with how T2Well works, but I have not actually used it. I recommend that you look at the user's guide, and examine the governing equations for wellbore flow to see whether…

Re: Coupled reservoir-wellbore model initialization (using T2Well)
I think you are correct that T=1 is too small for the EOS you are using. SATB is just the name of the subroutine where the code fails, but the important thing here is that for some reason the…

Re: Coupled reservoir-wellbore model initialization (using T2Well)
Try decreasing the wellbore permeability by a factor of 10. If that does not help decrease it more. You want wellbore permeability to be very high compared to reservoir permeability,…

Re: Coupled reservoir-wellbore model initialization (using T2Well)
I recommend making the permeability of the well material equal to the reservoir permeability for the initialization run. With no sources or sinks, it does not need to have high permeability.…

T2Well has TOUGH2 built into it, so it can model coupled reservoir-wellbore problems. We do not currently have a "T3Well" where TOUGH3 is coupled to a wellbore simulator.…
