Pressure
The Pressure node creates a boundary condition that acts as a pressure source at the boundary, which means that a constant acoustic pressure p0 is specified and maintained at the boundary: pt = p0. In the frequency domain, p0 is the amplitude of a harmonic pressure source. The node is also available from the Pairs submenu as an option at interfaces between parts in an assembly.
