Concentration
The Concentration node adds a boundary condition for the species concentrations: for example the following condition specifies the concentration of species, ci:
Concentration
Specify the concentration ci (SI unit: mol/m3) for each species individually. Select the check box for the species to specify the concentration, and enter a value or expression in the corresponding field. To use another boundary condition for a specific species, click to clear the check box for that species’ mass fraction.
