Interior Normal Impedance
Use the Interior Normal Impedance node to apply a transfer impedance condition on an interior boundary. The condition relates the normal stress at the two sides of the boundary (up and down) to the normal velocity via the normal transfer impedance Zn. The condition allows discontinuities (a slit) in pressure and temperature depending on the condition chosen for the temperature.
Interior Normal Impedance
Enter a value or expression for the Normal impedance Zn (SI unit: Pas/m).
Thermal
Select a Thermal conditionIsothermal (the default) or Adiabatic. See the Isothermal and Adiabatic conditions for further details.
