Inject gas at inlet boundary

[Yongqiang]

Dear David,

When coupling PhreeqcRM with a transport solver, the injected part is usually solution species. I wonder if gas can be injected at inlet instead of solution species.

PhreeqcRM allows you to define SOLUTION with SetConcentrations. You can use GAS_PHASE_MODIFY  to modify the moles of gas components present in a cell or EQUILIBRIUM_PHASE_MODIFY to modify the moles and target partial pressure of a gas.

You are on your own to figure out how you want to use these capabilities.
