Detailed Description

template<typename HyperbolicDescription, int dim, typename Number = double>
class ryujin::SolutionTransfer< HyperbolicDescription, 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 for the hyperbolic state,
• it interpolates the dynamic state, without limiting, on the continuous finite element space of OfflineData::dof_handler_cg().

Todo:

generalize the transfer of the dynamic state to support OfflineData::dof_handler_cg() and OfflineData::dof_handler_dg()

prepare_projection()

template<typename HyperbolicDescription , int dim, typename Number >

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

overridevirtual

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.

Implements ryujin::Interface::SolutionTransfer< dim, Number >.

project()

template<typename HyperbolicDescription , int dim, typename Number >

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

overridevirtual

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.

Implements ryujin::Interface::SolutionTransfer< dim, Number >.
