Re: Error Message
Hi Chris, You are of course right! Sorry that I did not take the time to figure out what the system was, i.e., what the dimensions, geometry, boundary conditions, etc.…

Re: Error Message
I throw in my two (contradicting) cents: (1) If you inject CO2 at a constant rate (not constant pressure!), the saturation in the pore space will stabilize at a value for which the effective…

Re: What is the expected format for the Grid Search input file?
@Héctor Ribera Remove the word "from" from the command line, or add > Computation; >> STOP; >>> IGNORE WARNINGS (you should see that recommendation at the bottom of the iTOUGH2 output file). Stefan

Re: What is the expected format for the Grid Search input file?
Hi Héctor, Just provide a simple list of all parameter sets you want to be evaluated. For example, if you have four parameters specified in the > PARAMETER block, create a text file with four columns,…

Re: Coupled Wellbore Flow
Hi Erick, Your table has to bracket all expected enthalpy and flow rate values you will encounter during the simulation. The error message tells you that an enthalpy of 971 kJ/kg is obtained,…

Re: Coupled Wellbore Flow
@ejimenez It looks like your f111a is not properly formatted. Can you please check by comparing it to Table 17 on page 68 of the TOUGH2 manual?

Re: Can't read MESH properly
@Rivan Tri Yuono You can use the positive values as permeability modifiers, as the message indicates. No need to change the mesh file.

Re: GENER BLOCK : water pumping EOS7r two phase problem
@AAgeoscience As indicated, this is possible in iTOUGH2 (it was implemented for exactly the same use case, i.e., water consumption due to a chemical reaction rather than pumping).…

Re: Hysteresis and non-wetting phase entrapment saturation

Re: Flux question
Just briefly: (1) Yes, what you see is the flow rate in kg/s (not flux in kg/s/m2), i.e., the same output as you see in the regular output file in the second output block (if you selected KDATA=2).…

Hi Mirco, I obviously don't know where exactly you put your natural-state mass sources, but once you turn them off, it is only natural that the pressure increase around these sources dissipates, i.e.…
