Description
Die Finite-Elemente-Methode, eines der wichtigsten in der Technik verwendeten numerischen Nherungsverfahren, wird hier grndlich und gut verstndlich, aber ohne ein Zuviel an mathematischem Formalismus abgehandelt. Insbesondere geht es um die Anwendung der Methode auf Strmungsprobleme. Alle wesentlichen aktuellen Forschungsergebnisse wurden in den Band aufgenommen; viele davon sind bisher nur verstreut in der Originalliteratur zu finden. Preface. 1. Introduction and preliminaries.
