Detailed Description

1d shock-shock setup.

Two streams of water move towards each other and collide at the discontinuity. Left state has positive momentum, right state has negative momentum of the same magnitude; the water height is identical on both sides.

Constructor & Destructor Documentation

ShockShock1d()

tsunami_lab::setups::ShockShock1d::ShockShock1d	(	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 positive to the left and negative to the right of the discontinuity.
i_location	x-coordinate of the discontinuity.

Author

Moritz Arnhold, Moritz Martin

DESCRIPTION

Implements the functions for a shock-shock problem, where to opposing streams of water crash into another

Member Function Documentation

getHeight()

tsunami_lab::t_real tsunami_lab::setups::ShockShock1d::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::ShockShock1d::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 (positive left of the discontinuity, negative right of it).

Implements tsunami_lab::setups::Setup.

getMomentumY()

tsunami_lab::t_real tsunami_lab::setups::ShockShock1d::getMomentumY ( t_real , t_real  ) const

virtual

Gets the momentum in y-direction.

Returns

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

Implements tsunami_lab::setups::Setup.
