Surface Roller Model in CMS - UNDER CONSTRUCTION
Governing Equation
The surface roller model is simulated as
| (1) |
where is the roller energy, are the roller propagation velocities, is the roller dissipation, is the wave dissipation (from CMS-Wave), and is an efficiency factor between 0 and 1 (default 1) which determines how much wave energy dissipation that goes into the roller.
