Nektar++ is a tensor product based finite element package designed to allow one to construct efficient classical low polynomial order h-type solvers (where h is the size of the finite element) as well as higher p-order piecewise polynomial order solvers.

The framework comes with a number of solvers and also allows one to construct a variety of new solvers.

The framework currently has the following capabilities:

  • Representation of one, two and three-dimensional fields as a collection of piecewise continuous or discontinuous polynomial domains.
  • Segment, plane and volume domains are permissible, as well as domains representing curves and surfaces (dimensionally-embedded domains).
  • Hybrid shaped elements, i.e triangles and quadrilaterals or tetrahedra, prisms and hexahedra.
  • Both hierarchical and nodal expansion bases.
  • Continuous or discontinuous Galerkin operators. ---Cross platform support for Linux, Mac OS X and Windows.
