Class
    Foam::StandardWallInteraction
 
Description
    Wall interaction model. Three choices:
    - rebound - optionally specify elasticity and resitution coefficients
    - stick   - particles assigined zero velocity
    - escape  - remove particle from the domain
 
    Example usage:
 
        StandardWallInteractionCoeffs
        {
            type        rebound; // stick, escape
            e           1;       // optional - elasticity coeff
            mu          0;       // optional - restitution coeff
        }
