Nektar++ [1] is an open-source MPI-based spectral element code that combines the accuracy of spectral methods with the geometric flexibility of finite elements, specifically, hp-version FEM. Nektar++ was initially developed by Imperial College London and is one of the ExaFLOW co-design applications being actively developed by the consortium. It supports several scalable solvers for many sets of partial differential equations, from (in)compressible Navier-Stokes to the bidomain model of cardiac electrophysiology.

It's always a bit of an embarrassment when talking about your code tests. I think most developers know that they don’t have enough tests or that their tests are not good enough.

There is never enough time to either write or to run tests that fully cover all possibilities so, like all types of programming, testing becomes a compromise where you try to make the best use of the limited resources available for testing.

Over the last year I've been working with Prof. Jon Essex of Southampton University on an ARCHER eCSE project with the pithy title of "Implementation of Dual Resolution Simulation Methodology in LAMMPS".  

So what do I mean by dual-resolution simulations?

September seems to have passed by in a bit of a blur, and it's already a whole month since the CP2K Summer School, which we ran at King's College London (23-26th August), so I thought it would be a good time to give an update on the recent activities of the CP2K-UK project.
