EULAG, a computational model for multiscale flows

EULAG (Eulerian/semi-Lagrangian fluid solver) is an established computational model for simulating thermo-fluid flows across a wide range of scales and physical scenarios. It is noteworthy for its nonoscillatory integration algorithms, robust elliptic solver, and generalized coordinate formulation enabling grid adaptivity technology. In this paper we highlight the key model ingredients, demonstrate its capabilities with a select subset of recent applications, and show its performance both in terms of accuracy and scalability on massively parallel processor architectures. A comprehensive list of references is provided to facilitate more detailed study.
