Class

Group
    grpLagrangianIntermediatePatchInteractionSubModels
 
Description
    Wall interaction model.
 
    Three choices:
      - rebound - optionally specify elasticity and restitution coefficients
      - stick   - particles assigned zero velocity
      - escape  - remove particle from the domain
 
    Example usage:
    \verbatim
    StandardWallInteractionCoeffs
    {
        type        rebound; // stick, escape
        e           1;       // optional - elasticity coeff
        mu          0;       // optional - (1 - restitution coeff)
    }
    \endverbatim
 
Note
  - \c mu=1 results in perfectly inelastic collisions.
