The development of parallel Computational Fluid Dynamics (CFD) codes is a challenging task that entails efficient parallelization concepts and strategies in order to achieve good scalability values when running those codes on modern supercomputers wi

In this paper, we present a framework that gives the user a tool at hand to explore large data sets from built infrastructure. In a first step we describe the integration of fully detailed product models of constructions delivering the geometric and

Zusammenfassung Numerische Simulation dient der Vorhersage und Analyse komplexer physikalischer Zusammenhänge, die im Gegensatz zum meist (deutlich) teureren Experiment am Rechner durchgeführt wird und damit beliebig oft wiederholt werden kann. Auf

In this work, we present methods for distributed domain generation within the constraints of our decentral domain management concept. Here, all participating actors only have knowledge of their immediate neighbours, which are defined by geometric and

We present simulations of real flood and tsunami events using a hybrid OpenMP-MPI model on high-performance cluster systems. The two-dimensional shallow water equations were solved by means of the in-house code NUFSAW2D, using an edge-based cell-cent

The multi-level hp-refinement scheme is a powerful extension of the finite element method that allows local mesh adaptation without the trouble of constraining hanging nodes. This is achieved through hierarchical high-order overlay meshes, a hp-schem

In this paper, we simulate overland flows using a cell-centred finite volume (CCFV) method with three solvers – HLLC, central-upwind, and artificial viscosity schemes – and present their parallel efficiency within the framework of our in-house co
