Detailed Description

Drives the chemistry step in the operator-split reactive transport loop.

Per timestep:

initializeChemicalSystemConcrete(...) / setChemicalSystemConcrete(...): For each chemical_system_id, store the transported totals \(c_{T\alpha}\), the current porous-medium state (porosity, mineral fractions, reactive surface area), and the process variables (e.g. temperature \(T\), pressure \(p\), time \(t\), and timestep \(\Delta t\)) in the corresponding ChemicalSystem. Each chemical_system_id is treated as one local batch reactor.
executeSpeciationCalculation(dt): Build PHREEQC input for all chemical_system_id, run PHREEQC via IPhreeqc, and obtain the reacted state after advancing chemistry over \(\Delta t\):
- updated aqueous composition,
- reaction/source terms \(R_{\alpha}\) for each transported component,
- updated mineral amounts.
updateVolumeFractionPostReaction(...), updatePorosityPostReaction(...): Apply precipitation / dissolution back into OpenGeoSys by updating mineral / solid volume fractions and porosity for each local system. These updates feed into flow / transport / mechanics in the next global step.
computeSecondaryVariable(...): Optionally expose derived quantities (e.g. pH fields, mineral fractions, surface loading) for output.

Accessors:

getConcentration(component_id, chemical_system_id): Reacted total \(c_{T\alpha}\) of a transported component for that local system after the last chemistry step. Used as the starting composition for the next transport solve.
getComponentList(): List of transported components in the order expected by the transport process.

Internal data:

_chemical_system holds the per-chemical_system_id definition (aqueous solution, kinetic and equilibrium reactants, exchangers, surface sites).
writeInputsToFile(), callPhreeqc(), readOutputsFromFile() implement PHREEQC I/O.

◆ executeSpeciationCalculation()

void ChemistryLib::PhreeqcIOData::PhreeqcIO::executeSpeciationCalculation ( double const dt )

overridevirtual

Run PHREEQC for all local chemical systems for the current timestep.

Uses the state previously provided by initializeChemicalSystemConcrete() / setChemicalSystemConcrete() for each chemical_system_id. Each local system is advanced as an isolated batch reactor over \(\Delta t\): no mass is exchanged between different systems inside PHREEQC.

PHREEQC returns, for each system:

updated aqueous composition,
reaction / source terms \(R_{\alpha}\) for each transported component,
updated mineral amounts and saturation state.

After this call completes, these reacted values are available for porosity update and for assembling the reaction/source term in the transport equation.

Parameters

dt	Timestep size \(\Delta t\) used for kinetic reactions.

Apply mineral precipitation / dissolution to the solid fraction in OGS.

Called after executeSpeciationCalculation(). For a given chemical_system_id, this function updates the solid / mineral inventory and related volume fractions based on the PHREEQC results for the last timestep.

Typical effect:

change in mineral volume fraction at this location,
updated solid composition available to mechanics / flow.
