Abstract

This paper describes and compares Eulerian (E) and Updated Lagrangian (UL) finite element algorithms for simulating film casting. It is found that the E algorithm is more accurate, faster and simpler to implement for one-dimensional film casting of a viscous fluid. However, the UL algorithm provides a natural and intuitive framework for accommodating viscoelasticity and for investigating the stability of the film.
