Hi Brian No problem. On that note, what is the purpose of "flush" in chemplugin? When there is inflow and outflow at an instance, isnt the solution anyway replaced with the inflowing solution in a chemplugin instance? I am also not sure how chemplugin handles kinetic minerals when the run is extended. When I extend the model, it seems like it is using the original kinetic mineral mass and not the endpoint mineral mass of the previous run. However, extend in chemplugin does use the endpoint solution chemistry and retain secondary minerals. I have tried to use the "pickup reactants" before the ExtendRun or within the original configuration but that doesnt work. cp_dam.Config("pickup reactants") cp_dam.ExtendRun(timeExt, "days") I have also tried to remove the kinetic minerals and then let it perform the pickup. But that also doesnt work. To test this I have included pyrite and calcite in the reservoir described above and then calcite was consumed in the 1st run. ExtendRun then starts again with the original calcite (and pyrite)content. However, it seems that secondary minerals in the system (like hematite) is retained. See the gtplot image below.

Hi I have constructed a chemplugin model where 2 streams flow into a reservoir (with volume 2000000 m3) and the outflow of the reservoir is the sum of the inflows. Everything seems to work fine except the reported pore volumes replaced (PV) which reports 0. See Por Vol below. The salt balance looks fine (after about 1 residence time the TDS in the dam is just above 50% of that of the streams), so I am wondering if PV is maybe just reporting incorrectly? Is PV only applicable to the initial reaction within a specific instance without consideration of the flow between the instances?
