Pressure
Use the Pressure node to define the boundary pressure at the pipe ends.
Pressure
Enter a value or expression for the Pressure p (SI unit: Pa). The default is 0 Pa.
In the frequency domain p represents the amplitude and phase (if it is complex valued) of a harmonic pressure source.
In the time domain enter an expression for the pressure p, for example, a forward moving sinusoidal wave of amplitude 1 Pa can be written as 1[Pa]*sin(omega*t-k*x), where omega and k are parameters defining the angular frequency and wave number, respectively.
