Detailed Description

LOCA abstract interface for continuation, derived from the NOX::Abstract::Group. This abstract class provides the interface necessary to perform continuation, i.e., compute families of solutions to .

Concrete implemenations of this interface must provide implementations of all of the methods in the NOX::Abstract::Group interface as well as the additional interface defined here.

Member Function Documentation

virtual NOX::Abstract::Group::ReturnType LOCA::MultiContinuation::AbstractGroup::computeDfDpMulti (  const vector< int > &  paramIDs, NOX::Abstract::MultiVector &  dfdp, bool  isValidF )  [pure virtual]

Compute for each parameter indexed by paramIDs. The first column of dfdp holds F, which is valid if isValidF is true. Otherwise F must be computed. Implemented in LOCA::MultiContinuation::FiniteDifferenceGroup.

void LOCA::MultiContinuation::AbstractGroup::projectToDraw (  const NOX::Abstract::Vector &  x, double *  px )  const [virtual]

Projects solution to a few scalars for multiparameter continuation. This method is called every time a solution is saved by the multiparameter continuation code MF for later visualization and should project the solution vector down to a few scalars. The array px will be preallocated to the proper length given by projectToDrawDimension(). The default implementation is the max norm of the vector. Reimplemented in LOCA::Epetra::Group, LOCA::EpetraNew::Group, and LOCA::LAPACK::Group.

int LOCA::MultiContinuation::AbstractGroup::projectToDrawDimension (   )  const [virtual]

Returns the dimension of the project to draw array. The default implementation is to return 1 since the default projection is the max norm of the vector (a scalar). Reimplemented in LOCA::Epetra::Group, LOCA::EpetraNew::Group, and LOCA::LAPACK::Group.
