If the Apply equilibrium condition on inflow boundaries check box is selected, the specified inflow concentration values in all active
Inflow boundary nodes for the physics interface are modified to comply with the equilibrium condition.
The list defaults to Equilibrium constant or select
User defined. For either option, the
Apply equilibrium condition on inflow boundaries check box is selected by default.
For Equilibrium constant, enter an
Equilibrium constant Keq (dimensionless). Also enter a value or expression for the
Unit activity concentration Ca0 (SI unit: mol/m
3). Selecting
Equilibrium constant defines an equilibrium condition based on the stoichiometric coefficients, the species activities, and the law of mass action.
Enter a value for the stoichiometric coefficientνc (dimensionless). The default is 0. Use negative values for reactants and positive values for products in the modeled reaction.
