Is it possible to compute a simulation with OH- as primary species?
Dear all, I would like to know if it is possible to compute a simulation by using a database with OH- as primary species. I used the kswitch utility in order to switch a database with H+ to OH- as…

Two time steps with restart gives different results than one without restart
Hello, Do you know why a restart during 6 hours (for example) after one time step (6 hours for example) is different from one time step of 12 hours? In my simulation with eos4,…

restart with surface complexation
Hello, I have been trying to run a restart with surface complexation. First, I get an error like that: "Restart time in INCHEM file is not the same as starting time for flow calculations. timetot= 3.…

zero flux for ions at boundary condition
Hello, When simulating a drying process of a porous media it is possible in TOUGH2 to apply a capillary pressure at the boundary condition. However, when doing such a simulation with a porous media…

Atmospheric Boundary Conditions
Hi all, I am confused with the boundary conditions that have to be imposed in an atmospheric boundary element for simulating evaporation with TOUGH2 (or TOUGHREACT). In a few slides (http://esd1.lbl.…

System of equations for EOS4
Hello, I am trying to write the system of equations for EOS4. But one equation is missing. I think it is the relation between mass fraction of water in gas phase (or mass fraction of air in gas…
