Where it is
Section titled “Where it is”Not a setup-tree node. Embedded in the application.
Controls
Section titled “Controls”No control on this panel carries a label that could be read from the source, so none is listed here. That is a limit of how this page is generated, not a statement that the panel is empty.

Sound pressure
Section titled “Sound pressure”Label changes with the case; the source gives these forms: Sound pressure, Normal velocity, Temperature disturbance, Impedance ratio.
- Control: value (
ValueField) - Value modes: none (plain entry)
The in-app guidance depends on the case:
- The amplitude that drives the cavity. Zero is a pressure-release surface — an open end at atmosphere — which is a real condition and not a mistake.
- Positive is the surface moving INTO the cavity.
- The disturbance driving the cavity thermally. Zero is a face that is present and not driving anything, the same way a zero pressure is for Harmonic.
- A ratio to ρc, not the absolute impedance — the solver applies air’s own 420 Pa·s/m itself. 1 is fully absorbing; upward of 10 is close to rigid.

Problems reported against this step
Section titled “Problems reported against this step”The application reports no problems against this step.
… marks a value the application computes at run time, so the source carries no fixed text for it.
