Re: Failure restarting Toughreact simulation.
Hi David, in addition to renaming the save and savechem files, in the flow.inp file the INCON block must be removed or renamed, that should solve your problem. Best regards, Lennard

Re: Helium diffusion into CO2 plume
Hello Carmen, just two guesses: trace gases can be written in the output in different units (I think partial pressure, mole fraction) which has to be chosen by igasflag in solute.inp record 7.…

Re: Geochemical Equilibrium between 2 water compositions
Hello David, as far as I know you cannot inject two water compositions, because you have to unequivocally assign the injection water composition to each cell in solute.inp.…

Dear Ella, just two short comments: I personally use TecPlot for Postprocessing and it works quite well. Maybe not best, but finally you can modify any parameter or visualisation you want.…

Re: Initial Geochemical Equilibrium between Minerals and Brine
The continuous mineral changes depend less on the brine composition, but rather on the primary mineral composition. If these are not (partially) stable against each other,…

Re: Species appear two times in time.out
Hi Jaeshik, you could also print out all of your Fe containing secondary species in plot.out and sum up all Fe(II) and Fe(III) species separately. This is a little laborious work,…

Re: Is there a limitation in the number of grid blocks to be printed out?
Hi Jaeshik, you can simply define the times of output in the flow.inp file. Then the spatial profiles of the components specified in solute.inp are written in the plot.out and solid.…

Re: Mass Balance for trace gases in TOUGHREACT V3-OMP
Dear all, I believe, I have found the reason for my mismatch observation. Obviously, it is connected with the formation of the dry-out zone. During the desiccation of a grid cell,…
