elements.catalog.mass_flow_outlet
elements.catalog.mass_flow_outlet(mdot, name='outlet', perturbation_bc=None)Prescribed-mass-flow outlet: the outflow rate is pinned to mdot.
The static pressure floats (it is whatever the interior produces); useful for a metered exhaust or as the mean-flow partner of a downstream choked throat whose critical mass flow is known.
This is an outflow-only boundary: mdot must be positive (positive means leaving the domain per element definition).
