| ▼Ndolfinx | Top-level namespace |
| ▼Ncommon | Miscellaneous classes, functions and types |
| CIndexMap | This class represents the distribution index arrays across processes. An index array is a contiguous collection of N+1 indices [0, 1, . . ., N] that are distributed across 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 indices to a unique global index |
| CScatterer | A Scatterer supports the MPI scattering and gathering of data that is associated with a common::IndexMap |
| CTimeLogger | Timer logging |
| CTimeLogManager | Logger initialisation |
| CTimer | A timer can be used for timing tasks. The basic usage is |
| ▼Nfem | Finite element method functionality |
| Npetsc | Helper functions for assembly into PETSc data structures |
| Nsparsitybuild | Support for building sparsity patterns from degree-of-freedom maps |
| CConstant | Constant value which can be attached to a Form |
| CCoordinateElement | A CoordinateElement manages coordinate mappings for isoparametric cells |
| CDirichletBC | Object for setting (strong) Dirichlet boundary conditions |
| CDofMap | Degree-of-freedom map |
| CElementDofLayout | The 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 |
| CExpression | Represents a mathematical expression evaluated at a pre-defined set of points on the reference cell |
| CFiniteElement | Finite Element, containing the dof layout on a reference element, and various methods for evaluating and transforming the basis |

| ▼Ngraph | Graph data structures and algorithms |
| Nbuild | Tools for distributed graphs |
| Nkahip | Interfaces to KaHIP parallel partitioner |
| CAdjacencyList | 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 |
| ▼Nio | Support for file IO |
| Ncells | Functions for the re-ordering of input mesh topology to the DOLFINx ordering, and transpose orderings for file output |
| Nxdmf_function | Low-level methods for reading/writing XDMF files |
| Nxdmf_mesh | Low-level methods for reading XDMF files |
| CADIOS2Writer | Base class for ADIOS2-based writers |
| CVTKFile | Output of meshes and functions in VTK/ParaView format |
| CXDMFFile | Read and write mesh::Mesh, fem::Function and other objects in XDMF |
| ▼Nla | Linear algebra interface |
| ▼Npetsc | PETSc linear algebra functions |
| Noptions | These 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 |
| CKrylovSolver | This class implements Krylov methods for linear systems of the form Ax = b. It is a wrapper for the Krylov solvers of PETSc |
| CMatrix | It is a simple wrapper for a PETSc matrix pointer (Mat). Its main purpose is to assist memory management of PETSc Mat objects |
| COperator | This class is a base class for matrices that can be used in petsc::KrylovSolver |
| CVector | A simple wrapper for a PETSc vector pointer (Vec). Its main purpose is to assist with memory/lifetime management of PETSc Vec objects |
| CMatrixCSR | Distributed sparse matrix |
| CSLEPcEigenSolver | This class provides an eigenvalue solver for PETSc matrices. It is a wrapper for the SLEPc eigenvalue solver |
| CSparsityPattern | Sparsity pattern data structure that can be used to initialize sparse matrices. After assembly, column indices are always sorted in increasing order. Ghost entries are kept after assembly |
| CVector | Distributed vector |
| RMatSet | Matrix accumulate/set concept for functions that can be used in assemblers to accumulate or set values in a matrix |
| ▼Nmesh | Mesh data structures and algorithms on meshes |
| CGeometry | Geometry stores the geometry imposed on a mesh |
| CMesh | A Mesh consists of a set of connected and numbered mesh topological entities, and geometry data |
| CMeshTags | MeshTags associate values with mesh topology entities |
| CTopology | Topology stores the topology of a mesh, consisting of mesh entities and connectivity (incidence relations for the mesh entities) |
| RMarkerFn | Requirements on function for geometry marking |
| ▼NMPI | MPI support functionality |
| CComm | A duplicate MPI communicator and manage lifetime of the communicator |
| Cdependent_false | |

| CTable | This class provides storage and pretty-printing for tables. Example usage: |
| Rscalar | This concept is used to constrain the a template type to floating point real or complex types. Note that this concept is different to std::floating_point which does not include std::complex |
