ClassId()

template<class TVar >

int TPZSolver< TVar >::ClassId ( ) const

overridevirtual

Define the class id associated with the class.

This id has to be unique for all classes A non unique id is flagged at the startup of the program

Implements TPZSavable.

Reimplemented in TPZMatrixSolver< TVar >, TPZStepSolver< TVar >, and TPZMGSolver< TVar >.

Clone()

template<class TVar>

virtual TPZSolver* TPZSolver< TVar >::Clone ( ) const

pure virtual

Clones the current object returning a pointer of type TPZSolver.

Implemented in TPZSequenceSolver< TVar >, TPZMGSolver< TVar >, TPZStepSolver< TVar >, and TPZCopySolve< TVar >.

Decompose()

template<class TVar>

virtual void TPZSolver< TVar >::Decompose ( )

inlinevirtual

Decompose the system of equations if a direct solver is used.

Reimplemented in TPZStepSolver< TVar >.

Definition at line 37 of file pzsolve.h.

ResetMatrix()

template<class TVar>

virtual void TPZSolver< TVar >::ResetMatrix ( )

inlinevirtual

This method will reset the matrix associated with the solver.

This is useful when the matrix needs to be recomputed in a non linear problem

Solve()

template<class TVar>

virtual void TPZSolver< TVar >::Solve ( const TPZFMatrix< TVar > &  F, TPZFMatrix< TVar > &  result, TPZFMatrix< TVar > *  residual = 0  )

pure virtual

Solves the system of linear equations.

Parameters

F	contains Force vector
result	contains the solution
residual	contains the residual for that linear system

Implemented in TPZStepSolver< TVar >, TPZMGSolver< TVar >, TPZCopySolve< TVar >, and TPZSequenceSolver< TVar >.

Referenced by TPZAnalysis::AnimateRun(), TPZMGAnalysis::Solve(), TPZEulerAnalysis::Solve(), and TPZAnalysis::Solve().

UpdateFrom()

template<class TVar>

virtual void TPZSolver< TVar >::UpdateFrom ( TPZAutoPointer< TPZMatrix< TVar > >  matrix )

inlinevirtual

Updates the values of the current matrix based on the values of the matrix.

Reimplemented in TPZMatrixSolver< TVar >, TPZMatrixSolver< REAL >, TPZMatrixSolver< TTVar >, TPZMatrixSolver< STATE >, TPZStepSolver< TVar >, and TPZSequenceSolver< TVar >.
