**Name of contributor**

Christoophe MaisondieuIFREMER - Applied Hydrodynamics Laboratory

**Simulation Method**

BEM, Boundary conditions developed to 2nd order

**Method for ****f**_{t}
computation

Derivatives of potential are directly given by resolution of integral equation. f_{t}and other time derivatives are computed the same way.

**Wave Absorption**

Wave absorbing beach (beach length = 2 * wave length)(Only used on free surface dynamic boundary condition.)

**Intersection**

The problem with singularities appear at both ends of the wedge could be solved by modification of normal directions at each extremity of the wedge. This option should be implemented soon.

**Number of nodes**

60 per wave length, 31 on wedge

**Time integral method**

4th order Runge-Kutta methodDt = T / 60 ( T : Heave period )
