Re: ECO2N, initial condition
Sawyer, NaN means "not-a-number" and it indicates that something went really wrong (divide by zero; square root of a negative number, overflow/underflow, etc.).…

Re: ECO2N, initial condition
Here's a quick comment and a few tips: (1) The system clearly has not reached steady state after 1000 time steps (I can tell from ST, DT and DX1) - I would therefore be impossible for me to guess…

Re: Atmosphere boundary thickness
Madjid, 1-1 It is essential that you fully understand the difference between RH (which is related to saturated vapor pressure and water mass fraction), and saturation (or water content),…

Re: Atmosphere boundary thickness
Madjid, The wind speed and surface roughness determine the thickness of the laminar boundary layer at the land surface. I do not know how the two are related, though.…

Re: MINC
Madjid, A sample input file is given in the TOUGH2 manual. It seems you want to run MINC twice. After you have generated the MINC file, remove the MESHM block. Regards, Stefan

Re: EOS7C-running problem
Hi Sara, I'm glad it works now. I suggest you consider which of the parameters affecting the pressure drawdown is most uncertain. I presume you know the pressure (which is the parameter you changed)…

Re: Well modeling
Quentin, Just a brief tip: (1) Don't use "all perfectly mobile" (it is unphysical). Use linear functions or Corey. (2) Set kz=1E-8, but kh equal to that of the formation (and.…

Re: EOS7C-running problem
Hi Sara, I'm sure there was an error message on your screen. But anyway, your pressure plot and the output file clearly show what is going on. You are pumping too much, pressure goes down,…

Re: Cauchy/Type III Boundary Condition
Amy, Try to represent the actual geometrical and physical conditions that lead to the Cauchy boundary. Depending on your application, you may want to add a thin extra element between the model…

Re: MINC
Madjid, (1) In MINC, you have a "fracture" continuum and a "matrix" continuum; you may subdivide the matrix continuum into multiple elements. Whether or not you want to further subdivide the matrix…

Re: Capillary Pressure Definition
Quentin, Capillary pressure is defined negative, i.e., it is the pressure in the wetting phase minus the pressure in the non-wetting phase, i.e., in Pc_ij,…

Re: heterogeneity

Re: How can I stop water movement in TMVOC?
Madjid, I looked at your output file and don't see any water fluxes. Please check again. Also, you set RP(1)=0.3, which is exactly the value of liquid saturation, not greater than the value,…

Re: Initial condition setting with MINC

Re: Fracture porosity when using MINC in Tough2
The only guideline I can give is to consider that local thermodynamic equilibrium is assumed within the fracture and matrix continuum. Stefan
