Detailed Description

A group representing the Moore-Spence turning point equations.

The LOCA::TurningPoint::MooreSpence::ExtendedGroup is a concrete implementation of the NOX::Abstract::Group, LOCA::MultiContinuation::AbstractGroup and LOCA::Extended::MultiAbstractGroup that defines the following extended set of equations that are regular at a generic turning point:

\[ G(z) = \left[ \begin{array}{c} F(x,p) \\ Jn \\ l^Tn-1 \end{array} \right] = 0 \]

where $z = [x, n, p]\in\Re^{2n+1}$, $x$ is the solution vector, $n$ is the null vector, $l$ is the length normalization vector and $J$ is the Jacobian of F.

The group stores an underlying group of type LOCA::TurningPoint::MooreSpence AbstractGroup to represent the equations $F(x,p) = 0$ and to manipulate the underlying Jacobian $J$. Note that the entire extended Jacobian $D_z G$ is not stored in memory, rather a block-elimination algorithm (bordering algorithm) is used to compute linear solves of the extended Jacobian (see LOCA::TurningPoint::MooreSpence::SolverFactory for more details).

This class implements all of the NOX::Abstract::Group, LOCA::MultiContinuation::AbstractGroup, and LOCA::Extended::MultiAbstractGroup methods for this extended set of equations and therefore is a complete group which can be passed to most NOX solvers to locate a single turning point or to the LOCA::Stepper to compute a family of turning points in a second parameter.

However, Jacobian-tranpose operations and gradient calculations cannot be implemented efficiently and therefore gradient-base nonlinear solvers such as steepest descent and Trust region methods cannot be used to solve the extended turning point equations.

The class is intialized via the tpParams parameter list argument to the constructor. The parameters this class recognizes are:

NOX::Abstract::Group::ReturnType LOCA::TurningPoint::MooreSpence::ExtendedGroup::computeF (  )  [virtual]

Compute the turning point equation residual $G$.

This method fills the extended residual

\[ G(z) = \left[ \begin{array}{c} F(x,p) \\ Jn \\ l^Tn-1 \end{array} \right]. \]

The solution component residual $F(x,p)$ and the null-vector residual $Jn$ are calculated via the computeF and applyJacobian methods of the underlying group.

NOX::Abstract::Group::ReturnType LOCA::TurningPoint::MooreSpence::ExtendedGroup::computeJacobian (  )  [virtual]

Compute the blocks of the Jacobian derivative of $G$.

This method computes the $J$, $\partial F/\partial p$, and $\partial Jn/\partial p$ blocks of the extended Jacobian:

\[ D_z G(z) = \begin{bmatrix} J & 0 & \frac{\partial F}{\partial p} \\ \frac{\partial Jn}{\partial x} & J & \frac{\partial Jn}{\partial p} \\ 0 & l^T & 0 \end{bmatrix} \]

by calling the computeJacobian, computeDfDp, and computeDJnDp methods of the underlying group. The second derivative matrix $\partial Jn/\partial x$ is not calculated since only its action on vectors is needed for linear solves using the bordering algorithm.

Computes the extended Jacobian vector product.

This method computes the extended Jacobian vector product

\[ \begin{bmatrix} J & 0 & \frac{\partial F}{\partial p} \\ \frac{\partial Jn}{\partial x} & J & \frac{\partial Jn}{\partial p} \\ 0 & l^T & 0 \end{bmatrix} \begin{bmatrix} a \\ b \\ c \end{bmatrix} = \begin{bmatrix} Ja + \frac{\partial F}{\partial p}c \\ \frac{\partial Jn}{\partial x}a + Jb + \frac{\partial Jn}{\partial p}c \\ l^T b \end{bmatrix} \]

using the applyJacobian and computeDJnDxa methods of the underlying group where $a$, $b$, and $c$ are the solution, null-vector, and paramter components of the given vector input. Vectors input and result must be of type LOCA::TurningPoint::MooreSpence::ExtendedVector, otherwise an error is thrown.
