Detailed Description

template<int dim, typename Number = double>
class ryujin::Interface::MeshAdaptor< dim, Number >

The interface of a MeshAdaptor: it decides, based on the current state, whether a mesh adaptation cycle should be performed, marks cells for coarsening and refinement, and/or may replace the transformation of the Discretization, i.e., change the geometry.

Transformation

template<int dim, typename Number = double>

using ryujin::Interface::MeshAdaptor< dim, Number >::Transformation = typename Discretization<dim>::Transformation

Definition at line 39 of file mesh_adaptor.h.

Constructor & Destructor Documentation

MeshAdaptor()

template<int dim, typename Number = double>

ryujin::Interface::MeshAdaptor< dim, Number >::MeshAdaptor ( const std::string &  subsection )

inlineexplicitprotected

A boolean indicating whether we should perform a mesh adaptation step in the current cycle. The analyze() method sets this boolean to true whenever an adaptation cycle should be performed. Constructor.

Member Function Documentation

prepare()

template<int dim, typename Number = double>

virtual void ryujin::Interface::MeshAdaptor< dim, Number >::prepare ( const Number  t )

pure virtual

Prepare temporary storage and clean up internal data for the analyze() facility.

Implemented in ryujin::MeshAdaptor< dim, Number >.

analyze()

template<int dim, typename Number = double>

virtual void ryujin::Interface::MeshAdaptor< dim, Number >::analyze ( const StateVector< Number > &  state_vector, const Number  t, unsigned int  cycle  )

pure virtual

Analyze the given StateVector and decide whether a mesh adaptation cycle should be performed. The result is available through need_mesh_adaptation().

Implemented in ryujin::MeshAdaptor< dim, Number >.

mark_cells_for_coarsening_and_refinement()

template<int dim, typename Number = double>

virtual void ryujin::Interface::MeshAdaptor< dim, Number >::mark_cells_for_coarsening_and_refinement ( dealii::Triangulation< dim > &  triangulation ) const

pure virtual

Mark cells for coarsening and refinement.

Implemented in ryujin::MeshAdaptor< dim, Number >.

update_transformation()

template<int dim, typename Number = double>

virtual void ryujin::Interface::MeshAdaptor< dim, Number >::update_transformation ( Transformation &  transformation ) const

pure virtual

Update the transformation of the Discretization that maps points of the triangulation to the actual geometry.

Member Data Documentation

need_mesh_adaptation_

template<int dim, typename Number = double>

bool ryujin::Interface::MeshAdaptor< dim, Number >::need_mesh_adaptation_

protected

Whether a mesh adaptation step should be performed in the current cycle.

Note

A derived class sets it in prepare() and analyze().
