elements.catalog.wall
elements.catalog.wall(name='wall', perturbation_bc=None)An impermeable single-port termination: mdot = 0 on its incident edge.
The wall blocks mean flow, so the leg behind it is stagnant (M = 0); its purpose is acoustic. By default it closes the perturbation problem as a rigid hard wall (u' = 0, R = +1) – which at the wall’s M = 0 state is identical to the inherited mdot' = 0 row. Pass perturbation_bc to model a non-rigid termination (e.g. a liner impedance) instead.
