Detailed Description

template<int dim>
class ryujin::Discretization< dim >

This class is as a container for data related to the discretization, this includes the triangulation, finite element, mapping, and quadrature. After prepare() is called, the getter functions Discretization::triangulation(), Discretization::finite_element(), Discretization::mapping(), and Discretization::quadrature() return valid const references to the mentioned objects.

The class uses dealii::ParameterAcceptor to handle a multitude of parameters to control the creation of meshes for a variety of benchmark configurations and to read in meshes in one of the formats supported by the deal.II library.

Member Typedef Documentation

Triangulation

template<int dim>

using ryujin::Discretization< dim >::Triangulation = typename Proxy<dim>::Triangulation

A type alias denoting the Triangulation we are using:

In one spatial dimensions we use a dealii::parallel::shared::Triangulation and for two and three dimensions a dealii::parallel::distributed::Triangulation.
