This inheritance list is sorted roughly, but not completely, alphabetically:
[detail level 12]
 Cdolfinx::graph::AdjacencyList< T >This class provides a static adjacency list data structure. It is commonly used to store directed graphs. For each node in the contiguous list of nodes [0, 1, 2, ..., n) it stores the connected nodes. The representation is strictly local, i.e. it is not parallel aware
 Cdolfinx::graph::BoostGraphColoringThis class colors a graph using the Boost Graph Library
 Cdolfinx::geometry::BoundingBoxTreeAxis-Aligned bounding box binary tree. It is used to find entities in a collection (often a mesh::Mesh)
 Cdolfinx::generation::BoxMeshTetrahedral mesh of the 3D rectangular prism spanned by two points p0 and p1. Given the number of cells (nx, ny, nz) in each direction, the total number of tetrahedra will be 6*nx*ny*nz and the total number of vertices will be (nx + 1)*(ny + 1)*(nz + 1)
 Cdolfinx::MPI::CommA duplicate MPI communicator and manage lifetime of the communicator
 Cdolfinx::function::Constant< T >A constant value which can be attached to a Form. Constants may be scalar (rank 0), vector (rank 1), or tensor valued
 Cdolfinx::fem::CoordinateElementThis class manages coordinate mappings for isoparametric cells
 Cdolfinx::fem::DirichletBC< T >Interface for setting (strong) Dirichlet boundary conditions
 Cdolfinx::fem::DiscreteOperatorsDiscrete gradient operators providing derivatives of functions
 Cdolfinx::fem::DofMapDegree-of-freedom map
 Cdolfinx::fem::ElementDofLayoutThe class represents the degree-of-freedom (dofs) for an element. Dofs are associated with a mesh entity. This class also handles sub-space dofs, which are views into the parent dofs
 Cdolfinx::function::Expression< T >Represents a mathematical expression evaluated at a pre-defined set of points on the reference cell. This class closely follows the concept of a UFC Expression
 Cfalse_type
 Cdolfinx::MPI::dependent_false< T >
 Cdolfinx::fem::FiniteElementFinite Element, containing the dof layout on a reference element, and various methods for evaluating and transforming the basis
 Cdolfinx::fem::Form< T >Class for variational forms
 Cdolfinx::function::Function< T >This class represents a function \( u_h \) in a finite element function space \( V_h \), given by
 Cdolfinx::function::FunctionSpaceThis class represents a finite element function space defined by a mesh, a finite element, and a local-to-global map of the degrees of freedom (dofmap)
 Cdolfinx::mesh::GeometryGeometry stores the geometry imposed on a mesh
 Cdolfinx::io::HDF5InterfaceThis class provides an interface to some HDF5 functionality
 Cdolfinx::common::IndexMapThis class represents the distribution index arrays across processes. An index array is a contiguous collection of N+1 block indices [0, 1, . . ., N] that are distributed across processes M processes. On a given process, the IndexMap stores a portion of the index set using local indices [0, 1, . . . , n], and a map from the local block indices to a unique global block index
 Cdolfinx::generation::IntervalMeshInterval mesh of the 1D line [a,b]. Given the number of cells (n) in the axial direction, the total number of intervals will be n and the total number of vertices will be (n + 1)
 Cdolfinx::mesh::MeshA Mesh consists of a set of connected and numbered mesh topological entities, and geometry data
 Cdolfinx::mesh::MeshTags< T >A MeshTags are used to associate mesh entities with values. The entity index (local to process) identifies the entity. MeshTags is a sparse data storage class; it allows tags to be associated with an arbitrary subset of mesh entities. An entity can have only one associated tag
 Cdolfinx::MPIThis class provides utility functions for easy communication with MPI and handles cases when DOLFINX is not configured with MPI
 Cdolfinx::nls::NewtonSolverThis class defines a Newton solver for nonlinear systems of equations of the form \(F(x) = 0\)
 Cdolfinx::nls::NonlinearProblemThis is a base class for nonlinear problems which can return the nonlinear function F(u) and its Jacobian J = dF(u)/du
 Cdolfinx::la::PETScKrylovSolverThis class implements Krylov methods for linear systems of the form Ax = b. It is a wrapper for the Krylov solvers of PETSc
 Cdolfinx::la::PETScOperatorThis class is a base class for matrices that can be used in PETScKrylovSolver
 Cdolfinx::la::PETScMatrixIt is a simple wrapper for a PETSc matrix pointer (Mat). Its main purpose is to assist memory management of PETSc Mat objects
 Cdolfinx::la::PETScOptionsThese class provides static functions that permit users to set and retrieve PETSc options via the PETSc option/parameter system. The option must not be prefixed by '-', e.g
 Cdolfinx::la::PETScVectorIt is a simple wrapper for a PETSc vector pointer (Vec). Its main purpose is to assist memory management of PETSc Vec objects
 Cdolfinx::generation::RectangleMeshTriangular mesh of the 2D rectangle spanned by two points p0 and p1. Given the number of cells (nx, ny) in each direction, the total number of triangles will be 2*nx*ny and the total number of vertices will be (nx + 1)*(ny + 1)
 Cdolfinx::fem::ReferenceCellGeometryTabulates the vertex positions for the reference cell
 Cdolfinx::la::SparsityPatternThis class provides a sparsity pattern data structure that can be used to initialize sparse matrices

 Cdolfinx::mesh::TopologyTopology stores the topology of a mesh, consisting of mesh entities and connectivity (incidence relations for the mesh entities)
 Cdolfinx::common::UniqueIdGeneratorThis is a singleton class that return IDs that are unique in the lifetime of a program
 Cdolfinx::la::Vector< T >Distributed vector
 Cdolfinx::la::VectorSpaceBasisThis class defines a basis for vector spaces, typically used for expressing nullspaces of singular operators and 'near nullspaces' used in smoothed aggregation algebraic multigrid
