A comparison of Eulerian and updated Lagrangian finite element algorithms for simulating film casting

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.
