Member Function Documentation

§ solve()

template<int dim>
virtual std::pair<double,double> aspect::StokesMatrixFreeHandler< dim >::solve ( )
pure virtual

Solves the Stokes linear system matrix-free. This is called by Simulator<dim>::solve_stokes().

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ setup_dofs()

template<int dim>
virtual void aspect::StokesMatrixFreeHandler< dim >::setup_dofs ( )
pure virtual

Allocates and sets up the members of the StokesMatrixFreeHandler. This is called by Simulator<dim>::setup_dofs()

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ assemble()

template<int dim>
virtual void aspect::StokesMatrixFreeHandler< dim >::assemble ( )
pure virtual

Perform various tasks to update the linear system to solve for. Note that we are not assembling a matrix (as this is a matrix-free algorithm), but we are evaluating the material model and storing the information necessary for a later call to solve().

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ build_preconditioner()

template<int dim>
virtual void aspect::StokesMatrixFreeHandler< dim >::build_preconditioner ( )
pure virtual

Computes and sets the diagonal for both the mass matrix operator and the A-block operators on each level for the purpose of smoothing inside the multigrid v-cycle.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ declare_parameters()

template<int dim>
static void aspect::StokesMatrixFreeHandler< dim >::declare_parameters ( ParameterHandler &  prm)
static

Declare parameters.

§ get_dof_handler_v()

template<int dim>
virtual const DoFHandler<dim>& aspect::StokesMatrixFreeHandler< dim >::get_dof_handler_v ( ) const
pure virtual

Return a reference to the DoFHandler that is used for velocity in the block GMG solver.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ get_dof_handler_p()

template<int dim>
virtual const DoFHandler<dim>& aspect::StokesMatrixFreeHandler< dim >::get_dof_handler_p ( ) const
pure virtual

Return a reference to the DoFHandler that is used for pressure in the block GMG solver.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ get_dof_handler_projection()

template<int dim>
virtual const DoFHandler<dim>& aspect::StokesMatrixFreeHandler< dim >::get_dof_handler_projection ( ) const
pure virtual

Return a reference to the DoFHandler that is used for the coefficient projection in the block GMG solver.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ get_constraints_v()

template<int dim>
virtual const AffineConstraints<double>& aspect::StokesMatrixFreeHandler< dim >::get_constraints_v ( ) const
pure virtual

Return a pointer to the object that describes the velocity DoF constraints for the block GMG Stokes solver.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ get_constraints_p()

template<int dim>
virtual const AffineConstraints<double>& aspect::StokesMatrixFreeHandler< dim >::get_constraints_p ( ) const
pure virtual

Return a pointer to the object that describes the pressure DoF constraints for the block GMG Stokes solver.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ get_mg_transfer_A()

template<int dim>
virtual const MGTransferMF<dim,GMGNumberType>& aspect::StokesMatrixFreeHandler< dim >::get_mg_transfer_A ( ) const
pure virtual

Return a pointer to the MGTransfer object used for the A block of the block GMG Stokes solver.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ get_mg_transfer_S()

template<int dim>
virtual const MGTransferMF<dim,GMGNumberType>& aspect::StokesMatrixFreeHandler< dim >::get_mg_transfer_S ( ) const
pure virtual

Return a pointer to the MGTransfer object used for the Schur complement block of the block GMG Stokes solver.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.

§ get_cell_data_memory_consumption()

template<int dim>
virtual std::size_t aspect::StokesMatrixFreeHandler< dim >::get_cell_data_memory_consumption ( ) const
pure virtual

Return the memory consumption in bytes that are used to store equation data like viscosity to be able to apply the operators.

Implemented in aspect::StokesMatrixFreeHandlerImplementation< dim, velocity_degree >.
