Member Function Documentation

virtual void itk::fem::SolverHyperbolic::AssembleElementMatrix (  Element::Pointer    e )  [virtual]

When assembling the element matrix into master matrix, we need to assemble the mass matrix too. Reimplemented from itk::fem::Solver.

virtual void itk::fem::SolverHyperbolic::FinalizeMatrixAfterAssembly (  void    )  [virtual]

Combines the M, C and K matrices into one big system of linear equations. Reimplemented from itk::fem::Solver.

virtual Float itk::fem::SolverHyperbolic::GetTimeStep (  void    )  const [inline, virtual]

Returns the time step used for dynamic problems. Reimplemented from itk::fem::Solver. Definition at line 72 of file itkFEMSolverHyperbolic.h. References itk::fem::Solver::Float, and m_deltaT.

virtual void itk::fem::SolverHyperbolic::InitializeLinearSystemWrapper (  void    )  [virtual]

Initialize the linear system wrapper. Reimplemented from itk::fem::Solver.

virtual void itk::fem::SolverHyperbolic::InitializeMatrixForAssembly (  unsigned int    N )  [virtual]

Initializes the storasge for all master matrices. Reimplemented from itk::fem::Solver.

virtual void itk::fem::SolverHyperbolic::SetTimeStep (  Float    dt )  [inline, virtual]

Sets the time step used for dynamic problems. Parameters: dt  New time step. Reimplemented from itk::fem::Solver. Definition at line 73 of file itkFEMSolverHyperbolic.h. References itk::fem::Solver::Float, and m_deltaT.

virtual void itk::fem::SolverHyperbolic::Solve (  void    )  [virtual]
