Pressure (Adiabatic)
Use the Pressure (Adiabatic) node to specify a prescribed pressure pbnd, that acts as a pressure source at the boundary, typically an inlet or outlet. In the frequency domain, pbnd is the amplitude of a harmonic pressure source. The adiabatic condition states that no heat flows into or out of the boundary:
This condition is in general not physically correct on a solid wall because solids are generally better thermal conductors than air.
Pressure
Enter the value of the Pressure pbnd (SI unit: Pa) at the boundary. The default is 0 Pa.
