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.

Friends And Related Function Documentation

◆ SolutionTransfer

template<int dim>

template<typename Discretization , int dim_, typename Number_ >

friend class SolutionTransfer

friend

In the SolutionTransfer class we need writable access to the triangulation object in order to prepare data for mesh adaptation and checkpointing / restart. Work around this issue by declaring the solution transfer class to be a friend rather than changing the constructor, or augmenting the methods in SolutionTransfer.
