Re: initial condition in EOS3 for volume elements with zero gas saturation
Youhanna, There are some fundamental misunderstandings. You have to decide for each element whether it has a single phase (either all liquid or all gas) or two-phase conditions - that ill determine…

Re: initial condition in EOS3 for volume elements with zero gas saturation
Under fully liquid saturated conditions, capillary pressure is zero, and thus the liquid pressure is equal to the gas pressure. So provide pressure, air mass fraction in the liquid phase,…

Re: why the SAVE disk file is empty even i have no error message when i run the input file
Madi, I noticed that you have elements assigned to material "FILL ", but your material name is actually "FILLI"; as a result, these elements are ignored,…

Re: Why a simulation with "same" input file once runs and once crashes?
Mona, Here is my (wild) guess: Check for files INCON, GENER, TABLE, MESH etc. sitting in your working directory. They have been created by the previous run,…

Re: Question about constant rate
Hi Quan, Again, if you have a very large volume for these "dummy" elements, they act as a Dirichlet boundary condition. Whatever you inject into these elements "disappears" into the large volume,…

Re: Question about constant rate
Hi Quan, Not sure what you mean by "dummy element". If this element has a zero or negative volume, it is by definition inactive (i.e., represents a boundary element with a Dirichlet boundary…

Re: Question on modeling landfill gas migration
Hamid, EOS7C is a stand-alone, TOUGH2-related simulator. It is available for licensing; see http://esd.lbl.gov/research/projects/tough/licensing/othertough.html. Stefan

Re: hi, I got interesting reseult seneario forecasting with fracture spacing(MINC) using Monte Carlo simulation.
As a first approximation, you could estimate/vary the fracture porosity instead of the fracture volume fraction. For example, whether you have a volume fraction (VF) of 2% combined with a porosity…

Re: Need help on using Ext.exe to generate Tecplot input file
Fang, Glad you figured it out. As I said a few replies ago, the MESH file just has to sit in the directory - you don't need to enter it on the EXT prompt.…

Re: Need help on using Ext.exe to generate Tecplot input file

There are several TOUGH-based THM codes, with different capabilities and at different stages of development and release. For a very brief overview, see Section 4.4 of the review article at http://dx.…
