Detailed Description

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

The SolutionTransfer class is an adaptation of the parallel::distributed::SolutionTransfer class and method implemented in deal.II. This class is, in contrast to the deal.II version, specifically tailored to our needs:

it uses the MultiComponentVector directly,
it implements a local mass matrix projection with convex limiting.

Member Function Documentation

◆ prepare_projection()

template<typename Description , int dim, typename Number >

void ryujin::SolutionTransfer< Description, dim, Number >::prepare_projection ( const StateVector & old_state_vector )

Prepare projection (and serialization) by registering a call back to all cells of the distributed triangulation. The call back attaches all necessary data to the triangulation to perform a projection after mesh adaptation, or a Triangulation::store()/load() operation.

Definition at line 80 of file solution_transfer.template.h.

References ryujin::have_separate_memory_spaces.

◆ project()

template<typename Description , int dim, typename Number >

void ryujin::SolutionTransfer< Description, dim, Number >::project ( StateVector & new_state_vector )

Project the data stored in the triangulation into a new state vector new_state_vector. The attached data either comes from a previous call to prepare_projection() prior to mesh adaptation or has been read back in from a checkpoint after a call to Triangulation::load().

Note: After mesh refinement all internal data structures stored in the OfflineData object must be reinitialized with a call to prepare() and the new_state_vector must be appropriately initialized with the new Partitioner.

Definition at line 391 of file solution_transfer.template.h.

References ryujin::have_separate_memory_spaces.

◆ get_handle()

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

unsigned int ryujin::SolutionTransfer< Description, dim, Number >::get_handle ( ) const

inline

Return the handle associated with the call back that was set by prepare_projection() and the associated data attached to the triangulation.

Definition at line 124 of file solution_transfer.h.

◆ set_handle()

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

void ryujin::SolutionTransfer< Description, dim, Number >::set_handle ( unsigned int handle )

inline

Set the handle associated data attached to the triangulation. This function has to be called after a Triangulation::load() operation and prior to the SolutionTransfer::project().

Definition at line 139 of file solution_transfer.h.

◆ reset_handle()

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

void ryujin::SolutionTransfer< Description, dim, Number >::reset_handle ( )

inline

Invalidate the currently stored handle. After a call to this function a new handle can be registered with prepare_projection(), or set_handle().
