Maybe this has been posted here, but I’ve only found a similar topic for ogs-5 but not ogs-6:
I am using the ComponentTransportProcess coupled with Phreeqc with a domain comprised of several different materials. Each material has, of course, a different ID to define corresponding properties in OGS.
What I haven’t been able to find out in the documentation is:
How to define different initial conditions for each process variable in each material? So far I can only define the same ICs for the whole domain, which is not correct, as each material has a different porewater concentration at t = 0.
