Mit diesem Buch lernen Sie, die physikalischen Grundlagen der mathematischen Modelle von Polymerprozessen zu durchschauen! Die in gestraffter Form abgefasste Einführung wendet sich weniger an den Mathematiker als an den praktisch tätigen Chemieingenieur. Spezielle Schemata der Finite-Elemente-Methode, die besonders zuverlässige und robuste numerische Lösungen von Polymerverarbeitungsmodellen liefern, werden ausführlich besprochen. Die Gleichungen der nicht-Newtonschen Strömungsmechanik werden in sich geschlossen, klar und eingängig beschrieben. Gut verständliche, einfache Codebeispiele können zur Modellierung einfacher Probleme verwendet oder für die Lösung komplexerer Aufgaben erweitert werden.
