**Simulation Method**

FVM

- Governing equations : 2-D incompressible NS eqs. with artificial compressibility
- Discretization : Cell-centered finite volume method
- Convective terms : 3rd order upwind biased scheme based on Roe's scheme with MUSCL approach
- Viscous terms : 2nd order central differencing
- Solution procedure : Approximate Newton-relaxation approach with sGS method of linear system
- Free surface cond. : Nonlinear kinematic condition and zero stress condition.

**Wave Absorption**

Wave absorbing beach (beach length = wave length)(Damping terms are added to kinematic B.C.)

**Number of meshes**

20 per wave length, 40 on wedge

**Time integral method**

2nd order backward Euler formulaDt = T / 540 ~ T / 700 ( T : Heave period )
