Unter Ausnutzung der objektorientierten Konzepte von C++ verfolgt das HiFlow\u00b3-Projekt einen modularen und generischen Ansatz f\u00fcr den Aufbau effizienter paralleler L\u00f6ser f\u00fcr numerische Probleme.

Dazu z\u00e4hlen etwa die Wechselwirkung tropischer Wirbelst\u00fcrme, den Blutfluss in der Aorta oder die Ausbreitung von Waldbr\u00e4nden und vieles mehr.<\/p>\n\n\n\n<p>Typische Anwendungen stammen aus der Medizintechnik, Meteorologie und Klimaforschung. Die Gemeinsamkeiten all dieser Probleme sind eine sehr hohe Komplexit\u00e4t der untersuchten Systeme, mathematische Modelle mit starken multiphysikalischen Kopplungen sowie hohe Anforderungen an die Computerressourcen wie Speicher und CPU-Geschwindigkeit. Aufgrund der gro\u00dfen Vielfalt an Modellen, Anforderungen und Zwecke der Problemstellungen m\u00fcssen in der Regel verschiedene Softwareaspekte in den Simulations- und Optimierungszyklen ber\u00fccksichtigt werden.
