Detailed Description

template<class Scalar = double, class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = KokkosClassic::DefaultNode::DefaultNodeType>
class MueLu::VariableDofLaplacianFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Factory for building scalar Laplace operator (that is used as fake operator for variable dof size problems)

Build distance Laplacian associated with input matrix A (which might have a variable number of DOFs per node). Coordinates are needed to calculate the distance laplacian values. The user-provided array "DofPresent" stores whether an array is present (=1) or not (=0) in the matrix. The length of the array is number of nodes * maxDofPerNode and therefore it might be larger or equal than the number of rows in the input matrix.

The factory produces the distance laplacian matrix A as output (with one dof per node) as well as the coarse version of the DofStatus (needed for the next coarser level), containing information about (artificial) Dirichlet rows in the matrix.

Input/output of VariableDofLaplacianFactory

User parameters of VariableDofLaplacianFactory

Parameter type default master.xml validated requested description
A Factory null * * Generating factory of the input matrix A with potentially variable number of DOFs. Might be padded or non-padded. Padded means, that the matrix has additional artificial rows and columns to have a constant number of DOFs per node.
Coordinates Factory null * * Generating factory for Coordinates needed for building distance laplacian.
DofPresent Teuchos::ArrayRCP<LocalOrdinal> NoFactory (*) Optional array containing information whether DOF is actually present in matrix or not.
Advanced Dirichlet: threshold double 1e-5 * Drop tolerance for Dirichlet detection
Variable DOF amalgamation: threshold double 1.8e-9 * Drop tolerance for amalgamation process
maxDofPerNode int 1 * Maximum number of DOFs per node

The * in the master.xml column denotes that the parameter is defined in the master.xml file.
The * in the validated column means that the parameter is declared in the list of valid input parameters (see VariableDofLaplacianFactory::GetValidParameters).
The * in the requested column states that the data is requested as input with all dependencies (see VariableDofLaplacianFactory::DeclareInput).
