|typedef unsigned int||subdomain_id|
|typedef unsigned int||global_dof_index|
|typedef unsigned char||boundary_id|
|typedef unsigned int||manifold_id|
|typedef unsigned char||material_id|
A namespace in which we declare typedefs for types used in deal.II, as well as special values for these types.
The type used for global indices of degrees of freedom. While in sequential computations the 4 billion indices of 32-bit unsigned integers is plenty, parallel computations using the parallel::distributed::Triangulation class can overflow this number and we need a bigger index space.
The data type always indicates an unsigned integer type.
|typedef unsigned char types::boundary_id|
The type used to denote boundary indicators associated with every piece of the boundary and, in the case of meshes that describe manifolds in higher dimensions, associated with every cell.
There is a special value, numbers::internal_face_boundary_id that is used to indicate an invalid value of this type and that is used as the boundary indicator for faces that are in the interior of the domain and therefore not part of any addressable boundary component.
