Detailed Description

Internal class, not part of the public API.

This class enables the storage of an interpolation matrix Wij mapping a source field Sj to a target field Ti via Ti=Vi^(-1).Wij.Sj. The matrix is built and stored on the processors belonging to the source group.

Constructor & Destructor Documentation

MEDCoupling::InterpolationMatrix::InterpolationMatrix	(	const MEDCoupling::ParaFIELD *	source_field,
		const ProcessorGroup &	source_group,
		const ProcessorGroup &	target_group,
		const DECOptions &	dec_opt,
		const InterpolationOptions &	i_opt
	)

! Creates an empty matrix structure linking two distributed supports. The method must be called by all processors belonging to source and target groups.

Parameters

source_support	local support
source_group	processor group containing the local processors
target_group	processor group containing the distant processors
method	interpolation method

Member Function Documentation

void MEDCoupling::InterpolationMatrix::addContribution	(	MEDCouplingPointSet &	distant_support,
		int	iproc_distant,
		const int *	distant_elems,
		const std::string &	srcMeth,
		const std::string &	targetMeth
	)

Adds the contribution of a distant subdomain to the* interpolation matrix. The method adds contribution to the interpolation matrix. For each row of the matrix, elements are addded as a (column, coeff) pair in the _coeffs array. This column number refers to an element on the target side via the _col_offsets array. It is made of a series of (iproc, ielem) pairs. The number of elements per row is stored in the row_offsets array.

param distant_support local representation of the distant subdomain param iproc_distant id of the distant subdomain (in the distant group) param distant_elems mapping between the local representation of the subdomain and the actual elem ids on the distant subdomain

void MEDCoupling::InterpolationMatrix::multiply ( MEDCouplingFieldDouble & field ) const

performs t=Ws, where t is the target field, s is the source field

The call to this method must be called both on the working side and on the idle side. On the working side, the vector T=VT^(-1).(W.S) is computed and sent. On the idle side, no computation is done, but the result from the working side is received and the field is updated.

Parameters

field source field on processors involved on the source side, target field on processors on the target side

void MEDCoupling::InterpolationMatrix::transposeMultiply ( MEDCouplingFieldDouble & field ) const

performs s=WTt, where t is the target field, s is the source field, WT is the transpose matrix from W

! The call to this method must be called both on the working side and on the idle side. On the working side, the target vector T is received and the vector S=VS^(-1).(WT.T) is computed to update the field. On the idle side, no computation is done, but the field is sent.

void MEDCoupling::InterpolationMatrix::prepare ( )

! The call to this method updates the arrays on the target side so that they know which amount of data from which processor they should expect. That call makes actual interpolations via multiply method available.
