Detailed Description

Example of a gaussian density distribution plus a constant density.

Parameters: a_smallPressure - Lower limit for pressure (returned) a_gamma - Gamma for polytropic, gamma-law gas a_ambientDensity - Ambient density add to the density gaussian a_deltaDensity - Mean of the gaussian a_pressure - If 0, use isentropic pressure if 1, use the constant pressure of 1.0 a_center - Center of the gaussian a_width - Width of the domain a_size - Standard deviation of the gaussian a_velocity - Initial velocity of the gas a_artvisc - Artificial viscosity coefficient

Member Function Documentation

void GaussianSmoothBC::setFortranCommon	(	Real &	a_smallPressure,
		const Real &	a_gamma,
		const Real &	a_ambientDensity,
		const Real &	a_deltaDensity,

		const Real &	a_artvisc
	)

Sets parameters in a common block used by Fortran routines.

PhysIBC* GaussianSmoothBC::new_physIBC

(

)

[virtual]

Factory method - this object is its own factory.

Return a pointer to a new PhysIBC object with m_isDefined = false (i.e., its define() must be called before it is used) and m_isFortranCommonSet set to value of m_isFortranCommonset in the current (factory) object.

Implements PhysIBC.

void GaussianSmoothBC::initialize

(

LevelData< FArrayBox > &

a_U

)

[virtual]

Set up initial conditions.

Implements PhysIBC.

void GaussianSmoothBC::primBC	(	FArrayBox &	a_WGdnv,
		const FArrayBox &	a_Wextrap,
		const FArrayBox &	a_W,
		const int &	a_dir,
		const Side::LoHiSide &	a_side,
		const Real &	a_time
	)			[virtual]

Set boundary primitive values.

Implements PhysIBC.

void GaussianSmoothBC::setBdrySlopes	(	FArrayBox &	a_dW,
		const FArrayBox &	a_W,
		const int &	a_dir,
		const Real &	a_time
	)			[virtual]

Set boundary slopes.

The boundary slopes in a_dW are already set to one sided difference approximations. If this function doesn't change them they will be used for the slopes at the boundaries.

Implements PhysIBC.

void GaussianSmoothBC::artViscBC	(	FArrayBox &	a_F,
		const FArrayBox &	a_U,
		const FArrayBox &	a_divVel,
		const int &	a_dir,
		const Real &	a_time
	)			[virtual]

Adjust boundary fluxes to account for artificial viscosity.

Implements PhysIBC.
