BC_p

hydrostatic pressure boundary conditions

Using the BC_p command, the user can specify boundary conditions for the hydrostatic pressure such as

BC_p($BCindex$) = ( %BND_inflow% ) BC_p($BCindex$) = ( %BND_outflow% ) BC_p($BCindex$) = ( %BND_AVERAGE% ) BC_p($BCindex$) = ( %BND_wall%, OPTIONAL: c_div , OPTIONAL: c_NUS ) BC_p($BCindex$) = ( %BND_free% )

These boundary conditions are applied when solving the Poisson equation for the hydrostatic pressure (see HydrostaticPressureAlgorithm). Additionally, if no boundary conditions are specified for the correction pressure (see CorrectionPressureAlgorithm), the hydrostatic pressure boundary conditions are used together with the dynamic pressure boundary conditions (see %ind_p_dyn%) to derive such boundary conditions.
