Typedef Documentation

using types::subdomain_id = typedef unsigned int

The type used to denote subdomain_ids of cells.

See the glossary for more information.

There is a special value, numbers::invalid_subdomain_id that is used to indicate an invalid value of this type.

Definition at line 43 of file types.h.

using types::global_vertex_index = typedef unsigned long long int

The type used for global indices of vertices.

Definition at line 48 of file types.h.

using types::global_dof_index = typedef unsigned long long int

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.

See the When to use types::global_dof_index instead of unsigned int page for guidance on when this type should or should not be used.

Definition at line 72 of file types.h.

using types::boundary_id = typedef unsigned int

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.

using types::manifold_id = typedef unsigned int

The type used to denote manifold indicators associated with every object of the mesh.

There is a special value, numbers::flat_manifold_id that is used to indicate the standard cartesian manifold.

using types::material_id = typedef unsigned int

The type used to denote material indicators associated with every cell.

There is a special value, numbers::invalid_material_id that is used to indicate an invalid value of this type.

Definition at line 134 of file types.h.

using types::blas_int = typedef int

Integer type in BLAS.

Definition at line 37 of file lapack_support.h.

using types::particle_index = typedef unsigned long long int

The type used for indices of particles. While in sequential computations the 4 billion indices of 32-bit unsigned integers is plenty, parallel computations using hundreds of processes can overflow this number and we need a bigger index space. We here utilize the same build variable that controls the dof indices because the number of degrees of freedom and the number of particles are typically on the same order of magnitude.

The data type always indicates an unsigned integer type.
