Implementation of the MGTransferBase interface for block matrices and simple vectors. This class uses MGTransferComponentBase selecting a single component or grouping several components into a single block. The transfer operators themselves are implemented for Vector and BlockVector objects.
See MGTransferBase to find out which of the transfer classes is best for your needs.

MGTransferSelect< number >::MGTransferSelect | ( | ) |
Constructor without constraint matrices. Use this constructor only with discontinuous finite elements or with no local refinement.
MGTransferSelect< number >::MGTransferSelect | ( | const ConstraintMatrix & | constraints | ) |
Constructor with constraint matrices.

Actually build the prolongation matrices for grouped components.
This function is a front-end for the same function in MGTransferComponentBase.
target_component
.If mg_target_component
is present, this refers to the renumbered components.
selected
argument
|
inline |
Change selected component. Handle with care!
Definition at line 440 of file mg_transfer_component.h.
|
virtual |
Prolongate a vector from level to_level-1
to level to_level
. The previous content of dst
is overwritten.
Implements MGTransferBase< Vector< number > >.
|
virtual |
Restrict a vector from level from_level
to level from_level-1
and add this restriction to dst
. If the region covered by cells on level from_level
is smaller than that of level from_level-1
(local refinement), then some degrees of freedom in dst
are active and will not be altered. For the other degress of freedom, the result of the restriction is added.
Implements MGTransferBase< Vector< number > >.

Transfer from multilevel vector to normal vector.
Copies data from active portions of an multilevel vector into the respective positions of a Vector.

The degrees of freedom on the the refinement edges. For each level (outer vector) and each dof index (inner vector), this bool is true if the level degree of freedom is on the refinement edge towards the lower level excluding boundary dofs.
