Properties

The acousticWaveTransmissive boundary condition provides a wave transmissive outflow condition, based on solving the following governing equation on the boundary.

\[\frac{D \, W f}{D t} = 0\]

where W is the wave speed and f is the field to which this boundary condition is applied.

Usage

The condition is specified in the field file using:

<patchName>
{
    // Mandatory entries
    type                acousticWaveTransmissive;
    advectiveSpeed      <scalar>;

    // Inherited entries
    ...
}
Property Description Type Required Default
type Type name: acousticWaveTransmissive word yes -
advectiveSpeed Advective speed value scalar yes -

The inherited entries are elaborated in:
