Class
    Foam::reboundVelocityLagrangianPatchVectorField
 
Description
    A rebound velocity boundary condition. Particles that hit a patch with this
    condition will rebound back into the volume of the mesh. The change in
    velocity is characterised by a coefficient of restitution and a fractional
    tangential momentum loss.
 
Usage
    \table
        Property | Description                         | Required? | Default
        e        | Coefficient of restitution          | yes       |
        mu       | Fractional tangential momentum loss | yes       |
    \endtable
 
    Example specification:
    \verbatim
    <LagrangianPatchName>
    {
        type            reboundVelocity;
        e               0.8;
        mu              10 [%];
    }
