Zusammenfassung

Dieses Kapitel ist der Genauigkeits- und Effizienzsteigerung und der Qualität numerischer Gitter für komplexe Geometrien gewidmet. Zuerst wird die Effizienzsteigerung durch Mehrgitteralgorithmen beschrieben, gefolgt von Beispielen. Adaptive Gittermethoden und lokale Gitterverfeinerung sind Gegenstand eines weiteren Abschnitts. Schließlich wird die Parallelisierung diskutiert. Besondere Aufmerksamkeit wird der Parallelverarbeitung für implizite Methoden, die auf der Gebietszerlegung in Raum und Zeit basieren, und der Analyse der Effizienz der Parallelverarbeitung gewidmet. Zur Veranschaulichung dieser Punkte werden Beispielberechnungen verwendet.
