backCyclePeriodicDomain()

void domain::backCyclePeriodicDomain

(

const double

backCycleDistance

)

Back cycle domain for periodic flows. Intended to be called some time after cyclePeriodicDomain is called. Splits the cell at posf.at(ngrd) - backCycleDistace, then moves end cells after the split to the beginning of the domain.

Parameters

<em>input:</em>

distance from the end to split and move the domain.

Definition at line 336 of file domain.cc.

cyclePeriodicDomain()

double domain::cyclePeriodicDomain

(

const int

icycle

)

Cycle domain for periodic flows.

Parameters

icycle

input: move all cells before and including this one to the end of the domain.

Returns

the cycle distance (used for backcycling).

Definition at line 304 of file domain.cc.

domainPositionToIndex()

int domain::domainPositionToIndex	(	double	position,
		const bool	LowSide,
		int	dbg )

Find index of cell for given position (residing in cell). Start search assuming a uniform grid, then search forward or back till hit the cell index. If position is on cell face j, then if LowSide true, return j, else j-1.
For start of eddy region, set LowSide to true
For end of eddy region, set LowSide to false
(This is so triplet maps don't overlap cells)

e.g., usual:   | { | | | | } |    5 pts, eddy pos between cell faces
      okay:    {   | | | |   }    5 pts, eddy pos on cell faces (1 or both)
      bad:     |   { | | }   |    5 pts, eddy pos on internal faces (1 or both)
                                                                                  

Parameters

position	input: position to find corresponding index.
LowSide	input: flag true, then return j if position is on cell face j, else j-1.

Returns

index of position.

init()

void domain::init	(	inputoutput *	p_io,
		meshManager *	p_mesher,
		streams *	p_strm,
		IdealGasPhase *	p_gas,
		Transport *	p_tran,
		micromixer *	p_mimx,
		eddy *	p_ed,
		domain *	p_eddl,
		solver *	p_solv,
		randomGenerator *	p_rand,
		bool	LisEddyDomain = false )

Initializer

Definition at line 46 of file domain.cc.

initEddyDomain()

void domain::initEddyDomain ( )

private

Initialize data members of the eddy domain. Note, none of the other members of this domain should be used (like random). Note, all variables here should have corresponding variables (by var_name) in the main domn. This is needed for using the eddl object.

Definition at line 167 of file domain.cc.

Ldomain()

double domain::Ldomain

(

)

Compute size of domain based on faces.

Definition at line 156 of file domain.cc.

setDomainFromRegion()

void domain::setDomainFromRegion	(	const int	i1,
		const int	i2 )

Set the domain from a region of the domn. Normally called by eddy domain.

Parameters

i1	input: index of starting cell of domn to build from
i2	input: index of ending cell of domn to build from If i2 < i1, we have a periodic region (wrap around the domain). This only happens in planar cases, not cylindrical or sphericial. nonwrap: | | * | * | * | * | * | * | | | i1 i2 new domain consists of *'d cells

Wrap: | 4 | 5 | | | | | 1 | 2 | 3 | i2 i1 New domain consists of #'d cells: 1 2 3 4 5}
