Effective relaxation methods are necessary for good multigrid convergence. For many
equations, standard Jacobi and Gauß–Seidel are inadequate, and more sophisticated …

Turbulence modelling in turbomachinery flows remains a challenge, especially when
transition and separation phenomena occur. Recently, several research efforts have been …

The use of composable abstractions allows the application of new and established
algorithms to a wide range of problems, while automatically inheriting the benefits of well …

Supersonic inlets are a key component of present and future air-breathing propulsion
systems for high-speed flight. The inlet design is challenging because of several …

Large-scale PDE simulations using high-order finite-element methods on unstructured
meshes are an indispensable tool in science and engineering. The widely used open …

A key problem in parallel programming is how data is partitioned: divided into subsets that
can be operated on in parallel and, in distributed memory machines, spread across multiple …

In this work, we introduce a new algorithm for N-to-M checkpointing in finite element
simulations. This new algorithm allows efficient saving/loading of functions representing …

The dual-bell nozzle is a promising concept for improving the performance of space
launchers. It is characterised by the presence of two altitude-dependent working modes …

We present a performance analysis appropriate for comparing algorithms using different
numerical discretizations. By taking into account the total time-to-solution, numerical …

We present a simple mathematical framework and API for parallel mesh and data
distribution, load balancing, and overlap generation. It relies on viewing the mesh as a …
