This paper presents the extension of the PEM scheme for the case of multidi
mensional wave problems. This is done on the basis of operator splitting an
d the PEM scheme for the one-dimensional wave equation given in the previou
s publication (V. Zalizniak, Commun. Numer. Meth. Engrg. 13 (3) (1997) 163-
171). Numerical results for two problems of wave propagation in comparison
with the analytical solutions are given to demonstrate the effectiveness of
the proposed method. for elastodynamics. (C) 1999 Elsevier Science S.A. Al
