✦ Synopsis

Mathematical models involving partial di erential equations (PDE) are widely used to describe many important chemical engineering problems. Here we focus our attention on a strategy to deal with systems of PDE whose solutions have contact discontinuities or shock-moving fronts. The solutions are calculated using Galerkin's method with piecewise polynomial of arbitrary degree basis in space. These basis functions are themselves time dependent through the time dependence of the nodal position. To show the capability and e ectiveness of our scheme we apply the moving ÿnite element method(MFEM) with piecewise polynomial of arbitrary degree to simulate a binary chromatographic process.

## Abstract Kinematical approach by limit analysis is one of the fundamental methods used to predict the plastic limit state and it is applied successfully to deal with engineering problems in solid mechanics. The kinematical approach consists of minimizing the plastic dissipation power throughout
