Detailed Description

Encompasses data and functions related to the application of boundary conditions. Topology of the boundaries itself is contained in the class Geometry.

Constructor & Destructor Documentation

BndConds::BndConds ( )

Initializes variables related to boundary conditions.

BndConds::~BndConds ( )

Finishes and cleans up the memory.

Member Function Documentation

void BndConds::AllocateMemory ( const Geometry & geometry )

Allocates all necessary memory.

Parameters

geometry geometrical data (number of boundary nodes at far-field)

Exceptions

std::bad_alloc failed memory allocation

void BndConds::BoundaryConditions	(	const Geometry &	geometry,
		FluidProps &	fluidProps,
		const Precond &	precond
	)

Sets boundary conditions at dummy points. In a first loop, b.c.'s at inlet, outlet and far-field are specified. In a second loop, b.c.'s are set for all solid walls.

Parameters

geometry	geometrical data
fluidProps	fluid properties
precond	low Mach-number preconditioning

void BndConds::Periodic	(	const Geometry &	geometry,
		CONSVARS	var[]
	)

static

Adds both parts of a conserved variables at all periodic boundaries. This function is utilized for residuals in TimeDiscr::Solve and in TimeDiscr::Irsmoo.

Parameters

geometry	geometrical data
var	variable of CONSVARS type

void BndConds::Periodic	(	const Geometry &	geometry,
		PRIMVARS	var[]
	)

static

Adds both parts of a primitive variables at all periodic boundaries. This function is utilized for gradients in SpaceDiscr::Gradients.

Parameters

geometry	geometrical data
var	variable of PRIMVARS type

void BndConds::Periodic	(	const Geometry &	geometry,
		REAL	var1[],
		REAL	var2[]
	)

static

Adds both parts of two REAL variables at all periodic boundaries. This function is utilized for gradients of T in SpaceDiscr::GradientsVisc.

Parameters

geometry	geometrical data
var1	first variable
var2	second variable

void BndConds::Periodic	(	const Geometry &	geometry,
		int	var[]
	)

static

Adds both parts of an integer variable at all periodic boundaries. This function is utilized for number of contributions in TimeDiscr::Irsmoo.

Parameters

geometry	geometrical data
var	variable of int type

void BndConds::ZeroResiduals	(	const Geometry &	geometry,
		Equations	equsType,
		CONSVARS	rhs[]
	)

static

Zeros out normal component of the residual at symmetry and at no-slip boundaries.

Parameters

geometry	geometrical data
equsType	equations solved (Euler or Navier-Stokes)
rhs	vector of residuals
