The Moving Wall condition is used to model a vibrating wall with harmonic variations. The condition is a variant of Myers’ condition used for the Impedance. See Ref. 1 and About the Moving Wall Boundary Condition located in the Theory Background for the Aeroacoustics Branch section for further details.

Select a Displacement: Inward normal displacement vn (SI unit: m) (the default), Displacement field vw (SI unit: m), Inward normal velocity un (SI unit: m/s), or Velocity field uw(SI unit: m/s). Then enter values or expressions based on the selection.
