**
Input Parameters** |

**
Elasticity Model
** |
**
To avoid excessive deformation (or
even inversion) of the elements near the deformable surface, the displacements
are absorbed by all the elements. The whole mesh can compress and expand
according to an elasticity model
implemented within the simulation software.
** |

**
Stabilization** |
**
To prevent surface waves from "crashing", causing an entanglement of the mesh, a mathematical model is incorporated into the simulation software to stabilize the surface during the first, highly turbulent phases of the simulation. The stabilization parameters can be relaxed when a steady-state flow is achieved.** |

**
Normalization
** |
**
For improved accuracy, the space dimensions of the domain are normalized. This avoids numbers that are too large or too small. In our case, the scale factor was 10, so that all the linear measurements in the input are in "decafeet."
** |

**
Convergence** |
**
Convergence parameters are used to stop the iterations after a certain accuracy has been reached.
** |

**
Output** |
**Files (data.out, mxyz.out) specifying the motion of the mesh and the values of the pressure and velocity at each node.** |

**
Governing Equations** |
**Navier-Stokes equations for viscous, incompressible fluid motion.** |
