Detailed Description

Functions to set initial conditions for the BSSN class. Functions are called via a config setting in VacuumSim class.

Function Documentation

void cosmo::bssn_ic_awa_linear_wave ( BSSN * bssn )

Initialize with a "linear" wave propagating in the x-direction.

AwA test.

void cosmo::bssn_ic_awa_linear_wave	(	BSSN *	bssn,
		real_t	A,
		int	dir
	)

Initialize with a "linear" wave propagating in the 'dir'-direction.

AwA test.

void cosmo::bssn_ic_awa_linear_wave_desitter ( BSSN * bssn )

Initialize with a "linear" wave propagating in the x-direction, on top of a deSitter spacetime.

Solution should behave, at linear order, as a damped wave equation. Should be run as a vacuum sim (todo: clean up)

void cosmo::bssn_ic_awa_stability	(	BSSN *	bssn,
		real_t	A
	)

Set flat vacuum spacetime initial conditions, plus small "noise" fluctuations.

Parameters

bssn	BSSN instance
