Nektar++


Nektar++ is a spectral/hp element framework designed to support the construction of efficient high-performance scalable solvers for a wide range of partial differential equations. The code is released as open-source under the MIT license. Although primarily driven by application-based research, it has been designed as a platform to support the development of novel numerical techniques in the area of high-order finite element methods.
Nektar++ is modern object-oriented code written in C++ and is being actively developed by members of the at Imperial College London and at the University of Utah.

Capabilities

Nektar++ includes the following capabilities:
Stable versions of the software are released on a 1-month basis and it is supported by an extensive testing framework which ensures correctness across a range of platforms and architectures.
Other capabilities currently under active development include p-adaption, r-adaption and support for accelerators.

Application domains

The development of the Nektar++ framework is driven by a number of aerodynamics and biomedical engineering applications and consequently the software package includes a number of pre-written solvers for these areas.

Incompressible flow

This solver time-integrates the incompressible Navier-Stokes equations for performing large-scale direct numerical simulation in complex geometries. It also supports the linearised and adjoint forms of the Navier-Stokes equations for evaluating hydrodynamic stability of flows.

Compressible flow

External aerodynamics simulations of high-speed compressible flows are supported through solution of the compressible Euler or Navier-Stokes equations.

Cardiac Electrophysiology

This solver supports the solution of the monodomain model and bidomain model of action potential propagation through myocardium.

Other application areas

Nektar++ is free and open source software, released under the MIT license.
