angularOscillatingDisplacement

Description

The angularOscillatingDisplacement is boundary condition that provides oscillating motion condition for moving patches.

Usage

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

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            angularOscillatingDisplacement;
    axis            <vector>;
    origin          <vector>;
    angle0          <scalar>;
    amplitude       <scalar>;
    omega           <scalar>;

    // Optional entries
    p0              <pointField>;

    // Inherited entries
    ...
}
