Class
Foam::waveDisplacementPointPatchVectorField
Description
Specified surface wave moving boundary.
The motion is a cosine wave with specified amplitude, frequency, wave number
and optional leading and trailing spatial ramps and temporal ramp
to allow the motion to be applied to an initially flat surface.
Usage
\table
Property | Description | Required | Default value
amplitude | Amplitude of the cosine wave | yes |
omega | Frequency of the cosine wave | yes |
waveNumber | Wave number of the cosine wave | no | (0 0 0)
startRamp | Leading ramp | no | 1
endRamp | Trailing ramp | no | 1
timeRamp | Temporal ramp | no | 1
\endtable
Example of the boundary condition specification:
\verbatim
<patchName>
{
type waveDisplacement;
value uniform (0 0 0);
amplitude (0 0.05 0);
omega 2;
waveNumber (5 0 0);
startRamp
{
type linearRamp;
duration 1;
start 4;
}
endRamp
{
type linearRamp;
duration 1;
start 4;
}
timeRamp
{
type linearRamp;
duration 1;
}
}
