The differentiation index has become an important tool for understanding systems of coupled differential and algebraic equations, referred to as DAEs in the process simulation community. More recently, this concept has been extended to coupled partial differential and algebraic equations. In this talk, a simulation problem from the chemical processing industry will be used to illustrate how high index model formulations lead to practical problems with dynamic simulation, and how index analysis can lead to model reformulations that permit successful simulation.
