Abstract (EN): The moving finite element method (MFEM) is developed using polynomial approximations of arbitrary degree in each of the finite elements. These approximations are obtained by the Lagrange interpolation polynomials, with the interior nodes optimized as in the orthogonal collaction method. The method can be used for any type of linear boundary conditions. A computer code is developed to illustrate the method with three examples: (i) the 1-D Burgers' problem; (ii) equilibrium model for fixed-bed absorption; and (iii) pseudo-homogenous axial dispersion model.
