Detailed Description

Abstract interface for the constraint portion of a constrained nonlinear system for constraints that support computing a solution component derivative as a multi-vector.

This class extends the LOCA::MultiContinuation::ConstraintInterface to support constraints that support computing the entire derivative with respect to the solution components (x) and storing the resulting derivative as a multivector. This interface adds one additional method, getConstraintDerivativesX(), that returns this derivative. Additionally, it implements the applyConstraintDerivativesX() methods using standard multi-vector operations.

NOX::Abstract::Group::ReturnType LOCA::MultiContinuation::ConstraintInterfaceMVDX::addDX (  Teuchos::ETransp  transb, double  alpha, const NOX::Abstract::MultiVector::DenseMatrix &  b, double  beta, NOX::Abstract::MultiVector &  result_x )  const [virtual]

Compute result_x = alpha * dg/dx^T * op(b) + beta * result_x. This method is implemented using getConstraintDerivativesX() and the NOX::Abstract::MultiVector::update() method. Implements LOCA::MultiContinuation::ConstraintInterface. Reimplemented in LOCA::MultiContinuation::CompositeConstraintMVDX.

virtual const NOX::Abstract::MultiVector* LOCA::MultiContinuation::ConstraintInterfaceMVDX::getDX (   )  const [pure virtual]

Return solution component of constraint derivatives. May return NULL if constraint derivative is zero Implemented in LOCA::MultiContinuation::ArcLengthConstraint, LOCA::MultiContinuation::CompositeConstraintMVDX, LOCA::MultiContinuation::MultiVecConstraint, LOCA::MultiContinuation::NaturalConstraint, and LOCA::TurningPoint::MinimallyAugmented::Constraint.

NOX::Abstract::Group::ReturnType LOCA::MultiContinuation::ConstraintInterfaceMVDX::multiplyDX (  double  alpha, const NOX::Abstract::MultiVector &  input_x, NOX::Abstract::MultiVector::DenseMatrix &  result_p )  const [virtual]

Compute result_p = alpha * dg/dx * input_x. This method is implemented using getConstraintDerivativesX() and the NOX::Abstract::MultiVector::multiply() method. Implements LOCA::MultiContinuation::ConstraintInterface. Reimplemented in LOCA::MultiContinuation::CompositeConstraintMVDX.
