[tag] equation_balance_type

This indicates whether the governing equation is a volume balance or a mass balance. Its value can be volume or mass. If it is set to volume, note that the phase density must be constant, and the unit of the Neumann boundary condition for the fluid phase is m/s. Otherwise, the unit of the Neumann boundary condition is kg/m^3*m/s = kg/m^2/s. Default value is volume.
