waveMaker

Description

The waveMaker is a boundary condition that provides a point motion boundary condition to generate waves based on either piston or flap motions.

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            waveMaker;
    motionType      <word>;
    n               <vector>;
    initialDepth    <scalar>;
    wavePeriod      <scalar>;
    waveHeight      <scalar>;
    wavePhase       <scalar>;
    rampTime        <scalar>;

    // Optional entries
    waveAngle       <scalar>;
    startTime       <scalar>;
    secondOrder     <bool>;
    nPaddle         <label>;

    // Inherited entries
    ...
}
