High-order polynomial expansions

Nektar++ can use high-order polynomial bases on each element to provide faster convergence rates compared with linear finite elements.

Industry-relevant implicit LES via spectral/hp element methods

Industry-relevant implicit LES via spectral/hp element methods
We present the successful deployment of high-fidelity Large-Eddy Simulation (LES) technologies based on spectral/hp element methods (SEM) to an industry-relevant configuration. The simulation is carried out on a real automotive car, namely the Elemental Rp1 model.
