Detailed Description

template<int dim, typename Number>
class ExaDG::DeformedMappingBase< dim, Number >

Base class to describe grid deformations, where the grid coordinates described by a reference mapping are superimposed by a displacement DoF vector.

A typical use case of this class are Arbitrary Lagrangian-Eulerian type problems with moving domains / grids, where the displacement vector describes the time-dependent deformation of the grid. However, this class may also be used for stationary problems, e.g. to apply high-order curved boundaries on top of low-order approximation of a certain geometry.

TODO: extend this class to simplicial elements.

Constructor & Destructor Documentation

DeformedMappingBase()

template<int dim, typename Number>

ExaDG::DeformedMappingBase< dim, Number >::DeformedMappingBase ( std::shared_ptr< dealii::Mapping< dim > const > mapping_undeformed, unsigned int const mapping_degree_deformed, dealii::Triangulation< dim > const & triangulation )

inline

Constructor.

The constructor assumes a vanishing displacement field, i.e. after construction the reference configuration described by mapping_undeformed describes the absolute coordinates of the grid.

~DeformedMappingBase()

template<int dim, typename Number>

virtual ExaDG::DeformedMappingBase< dim, Number >::~DeformedMappingBase ( )

inlinevirtual

Desctructor.

Member Function Documentation

print_iterations()

template<int dim, typename Number>

virtual void ExaDG::DeformedMappingBase< dim, Number >::print_iterations ( ) const

inlinevirtual

Print the number of iterations for PDE-type grid deformation problems.

TODO: this function is only relevant for PDE-type grid deformation problems, and should therefore not appear in this base class.

Reimplemented in ExaDG::Poisson::DeformedMapping< dim, Number >, and ExaDG::Structure::DeformedMapping< dim, Number >.

update()

template<int dim, typename Number>

virtual void ExaDG::DeformedMappingBase< dim, Number >::update ( double const time, bool const print_solver_info, types::time_step time_step_number )

pure virtual

Updates the mapping, i.e., moves the grid.

TODO: The parameters print_solver_info and time_step_number are only relevant for PDE-type grid deformation problems. Hence this function with these particular arguments should not appear in this base class.

Implemented in ExaDG::DeformedMappingFunction< dim, Number >, ExaDG::Poisson::DeformedMapping< dim, Number >, and ExaDG::Structure::DeformedMapping< dim, Number >.
