Detailed Description

template<class Scalar = DefaultScalar, class LocalOrdinal = DefaultLocalOrdinal, class GlobalOrdinal = DefaultGlobalOrdinal, class Node = DefaultNode>
class MueLu::UnsmooshFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Factory for building "unsmooshed" transfer operators from transfer operators associated with a scalar helper problem (built by the VariableDofLaplacianFactory)

The output prolongation operator P is compatible to the input matrix A. The input prolongation matrix P is supposed to be built by the VariableDofLaplacianFactory with 1 DOF per node. The DofStatus array declares for each row, whether it is a standard dof or a padded/pseudo Dirichlet dof. The user has to provide the parameter "maxDofPerNode", since the coarse matrices are always padded by construction (i.e. constant number of DOFs per node). This parameter is needed for building the column map of the unsmooshed prolongation operator. The parameter "fineIsPadded" allows to specify whether the input matrix A on the finest level is padded or not. In the padded case we have an artificially extended input matrix with pseudo Dirichlet rows on inactive rows. In the non-padded version we have "variable" number of Dofs per node.

Input/output of UnsmooshFactory

User parameters of UnsmooshFactory

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. Needed to match the row map for the unsmooshed version of P with the row map of the unamalgamated input matrix A.
P Factory null * * Generating factory of the (amalgamated) prolongator P generated from a (pseudo Laplacian) with 1 Dofs per node. Will be unsmooshed to be compatible with input matrix A in this factory.
DofStatus Facotry null * * Generating factory for dofStatus array (usually generated by the VariableDofLaplacdianFactory). It is a Teuchos::Array<char> of size number of Rows of input matrix P multiplied by the maximum possible number of Dofs per node.
maxDofPerNode int 1 * Maximum number of DOFs per node. Needed for generating unsmooshed P. Note, that the coarse matrices are always padded, i.e. we have constant number of DOFs per node.

fineIsPadded | bool | false | * | | True if finest level input matrix is padded (default is false)

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 UnsmooshFactory::GetValidParameters).
The * in the requested column states that the data is requested as input with all dependencies (see UnsmooshFactory::DeclareInput).
