Type-Bound Procedures

procedure, public :: CountRemoteMortarSides => CountRemoteMortarSides_DomainDecomposition_t

public function CountRemoteMortarSides_DomainDecomposition_t(this, mortarInfo, nMortars, nSub) result(nRemote)

Counts the mortar sub-sides this rank exchanges over MPI: those where exactly one of the big side and the sub-side is owned by this rank. A mortar entirely on one rank is served from memory, and one entirely on other ranks is not this rank's to carry.

Arguments

Type	Intent	Attributes		Name
class(DomainDecomposition_t),	intent(in)		::	this
integer,	intent(in),	pointer	::	mortarInfo(:,:)
integer,	intent(in)		::	nMortars
integer,	intent(in)		::	nSub

Return Value integer

procedure, public :: CountRemoteSides => CountRemoteSides_DomainDecomposition_t

public function CountRemoteSides_DomainDecomposition_t(this, sideInfo, nElem, nSidesPerElem) result(nRemote)

Counts the conforming sides of the local elements whose neighbor element is owned by another rank -- the sides an exchange sends and receives over MPI.

Arguments

Type	Intent		Name
class(DomainDecomposition_t),	intent(in)	::	this
integer,	intent(in)	::	sideInfo(1:5,1:nSidesPerElem,1:nElem)
integer,	intent(in)	::	nElem
integer,	intent(in)	::	nSidesPerElem

Return Value integer

procedure, public :: GenerateDecompositionFromOffsets => GenerateDecompositionFromOffsets_DomainDecomposition_t

public subroutine GenerateDecompositionFromOffsets_DomainDecomposition_t(this, offsetElem, maxMsg)

Builds the decomposition from a prescribed contiguous partition rather than from the balanced one GenerateDecomposition computes. Rank r-1 (r = 1..nRanks) owns global elements offsetElem(r)+1 .. offsetElem(r+1), and the global element count is offsetElem(nRanks+1).
