DESCRIPTION

Two-dimensional circular dam break with submarine Gaussian bump.

Member Function Documentation

getBathymetry()

tsunami_lab::t_real tsunami_lab::setups::CircularDamBreakObstacle2d::getBathymetry ( t_real i_x, t_real i_y ) const

virtual

Bathymetry b = OBSTACLE_PEAK · exp(-r_obs² / (2 σ²)).

Implements tsunami_lab::setups::Setup.

getHeight()

tsunami_lab::t_real tsunami_lab::setups::CircularDamBreakObstacle2d::getHeight ( t_real i_x, t_real i_y ) const

virtual

Water column h = η - b at the queried point. Keeps η at the piecewise-constant base level so lake-at-rest holds outside the dam.

Implements tsunami_lab::setups::Setup.

getMomentumX()

tsunami_lab::t_real tsunami_lab::setups::CircularDamBreakObstacle2d::getMomentumX ( t_real , t_real  ) const

virtual

Momentum in x-direction (always 0 — initial state at rest).

Implements tsunami_lab::setups::Setup.

getMomentumY()

tsunami_lab::t_real tsunami_lab::setups::CircularDamBreakObstacle2d::getMomentumY ( t_real , t_real  ) const

virtual

Momentum in y-direction (always 0).

Implements tsunami_lab::setups::Setup.
