Member Function Documentation

getSurfaceElevation()

virtual double IBAMR::StokesWaveGeneratorStrategy::getSurfaceElevation ( double  x, double  time  ) const

pure virtual

Get surface elevation at a specified horizontal position and time.

Implemented in IBAMR::IrregularWaveGenerator, IBAMR::FifthOrderStokesWaveGenerator, and IBAMR::FirstOrderStokesWaveGenerator.

getVelocity()

virtual double IBAMR::StokesWaveGeneratorStrategy::getVelocity ( double  x, double  z_plus_d, double  time, int  comp_idx  ) const

pure virtual

Get velocity component at a specified position and time.

Note

We assume that the bottom left corner of the numerical wave tank is at (0,0) in 2D or at (0,0,0) in 3D. The

Parameters

z_plus_d	is the \( y \) (in 2D) or the \( z \) (in 3D) coordinate of a point in the numerical wave tank. In partcular
z_plus_d	is not with respect to free-surface as generally taken in some textbooks.

Implemented in IBAMR::IrregularWaveGenerator, IBAMR::FifthOrderStokesWaveGenerator, and IBAMR::FirstOrderStokesWaveGenerator.
