Re: FOR parameter under PARAM.3
@kenny Ah, and in MULTI.f90 with the source term, FAC=FORD/EVOL(J), where FORD=FOR*DELTEX. I have a bespoke source term coded in MUTLI.f90, and I know where there are peaks in pressure associated…

FOR parameter under PARAM.3

I recently changed the default value of the `FOR` parameter under PARAM.3 in TOUGH3 (EOS5) from 1.0 to 0.5. Upon reviewing the output, I noticed the time values in the time-series data seem to be…

Re: Mass balance assessment with TOUGH3
@Kenny Is the duplication of connections across partitioned domain interfaces necessary to correctly resolve fluxes between subdomains? Specifically, does TOUGH3 require two sets of connection…

Re: TOUGH3 installation issue
Has it been noted that when installing TOUGH3 with a Fortran compiler version 9 or higher, certain restrictions apply to the version of PETSc that can be used? In particular,…

Re: Mass balance assessment with TOUGH3
Having taken a deeper dive, it turned out that duplicate connection data was being printed out. I will need to look at this, and see how/where our source code deviates from the latest clean build.

Re: Mass balance assessment with TOUGH3
Thank you Eric! You are not the first one to suggest this today. I will take a closer look at the flux calculations and report back.

Mass balance assessment with TOUGH3

I am looking to validate the observed mass balance agains the theoretical (initial + source/sink - migration form domain into boundary cells) in a TOUGH3 with Neumann boundary conditions.…

Use of AMRES in TOUGH3

It appears that the `AMRES` parameter is defunct in TOUGH3 (see Main_Comp.f90). However, I am having issues of exceesive residuals which break PETSc. Are there any plans to implement a fix for…
