Detailed Description

1d rare-rare setup.

Two streams of water move away from each other, producing two rarefaction waves that travel outwards from the discontinuity. Left state has negative momentum, right state has positive momentum of the same magnitude; the water height is identical on both sides.

Constructor & Destructor Documentation

RareRare1d()

tsunami_lab::setups::RareRare1d::RareRare1d	(	t_real	i_height,
		t_real	i_momentum,
		t_real	i_location )

Constructor.

Parameters

i_height	water height on both sides of the discontinuity.
i_momentum	magnitude of the momentum; applied negative to the left and positive to the right of the discontinuity.
i_location	x-coordinate of the discontinuity.

Author

Moritz Arnhold, Moritz Martin

DESCRIPTION

Implements the functions for a rare-rare problem, where to streams of water diverge from another

Member Function Documentation

getHeight()

tsunami_lab::t_real tsunami_lab::setups::RareRare1d::getHeight ( t_real , t_real  ) const

virtual

Gets the water height at a given point.

Returns

water height.

Implements tsunami_lab::setups::Setup.

getMomentumX()

tsunami_lab::t_real tsunami_lab::setups::RareRare1d::getMomentumX ( t_real i_x, t_real  ) const

virtual

Gets the momentum in x-direction.

Parameters

i_x	x-coordinate of the queried point.

Returns

momentum in x-direction (negative left of the discontinuity, positive right of it).

Implements tsunami_lab::setups::Setup.

getMomentumY()

tsunami_lab::t_real tsunami_lab::setups::RareRare1d::getMomentumY ( t_real , t_real  ) const

virtual

Gets the momentum in y-direction.

Returns

momentum in y-direction (always 0 in the 1d rare-rare setup).

Implements tsunami_lab::setups::Setup.
