Detailed Description

sparse projection operators for mixed FEM.

NAME: MxProj - sparse projection operators for mixed FEM

DESCRIPTION:

This projection operator interpolates a field using a "MatSparse" representation. The "MatSparse" is filled automatically once given access to the "DegFreeFE" objects for the two involved grids.

In contrast to the parent class "ProjInterpSparse", this class handles the case of general numbering. The projection operator is build upon the following assumptions: (i) the fields are orthogonal, and (ii) the fields use the same geometry grid.

See ProjInterpSparse, for a more precise description of the matematical properties of the projection.

Constructor & Destructor Documentation

MxProj::MxProj ( const char * description_ = "Projector operator for general numbering" )

See class "Proj". Notice that two "DegFreeFE" objects must be supplied by use of "rebindDOF".

MxProj::MxProj ( const Proj_prm &,

const char * description_ = "Projector operator for general numbering" )

See documentation of one of the overloaded constructor.
