Detailed Description

template<typename Description, int dim, typename Number = double>
class ryujin::SolutionTransfer< Description, dim, Number >

A solution transfer class that interpolates a given state U (in conserved variables) to a refined/coarsened mesh. The class first transforms the conserved state into primitive variables and then interpolates/restricts the primitive state field via deal.II's SolutionTransfer mechanism.

Member Function Documentation

prepare_for_interpolation()

template<typename Description , int dim, typename Number = double>

void ryujin::SolutionTransfer< Description, dim, Number >::prepare_for_interpolation ( const vector_type &  U )

inline

Read in a state vector (in conserved quantities). The function populates an auxiliary distributed vectors that store the given state in primitive variables and then calls the underlying deal.II SolutionTransfer::prepare_for_coarsening_and_refinement();

This function has to be called before the actual grid refinement.

interpolate()

template<typename Description , int dim, typename Number = double>

void ryujin::SolutionTransfer< Description, dim, Number >::interpolate ( vector_type &  U )

inline

Finalize the state vector transfer by calling SolutionTransfer::interpolate() and repopulating the state vector (in conserved quantities).

This function has to be called after the actual grid refinement.
