In this paper, we extend the use of automatic rezoning to viscous flow in two dimensions. In a previous paper, we tested this technique on inviscid flow, with very good results. To simulate viscosity, we follow Fishelov's idea of explicitly taking the Laplacian of the cutoff function, but unlike Fis

We develop a class of higher-order mixed ยฎnite dierence methods for elliptic partial dierential equations. The problem is recast as a ยฎrst-order mixed system and the higher-order compact schemes follow as a natural extension of the formulations we developed previously for the scalar PDE problem. Sin

Alternate direction methods are based on the Lie formula (eA/"ea/n)" -e '~+s = O(l/n) for square matrices A and B. A more precise formula is known: (eA/2"eS/"e~/2")" -e a+a = O(1/n2). The search for more accurate product formulae is negative, in the following sense: there is no integer k and no choi
