This paper is concerned with computational mesh of the Marker and Cell method. The comutational stability of the finite difference equations which is based on the MAC method, using non-uniform mesh, is examined with respect to trucation errors and energy conservance of the finite difference equation. And restrictions for accurate finite difference calculations, using Mesh Reynolds No. and Flow-Local Reynolds No., are proposed. Those are, (1) R_m<20 (2) R_m<√<R_l> R_m : Mesh Reynolds No. R_l : Flow-Local Reynolds No. These ristrictions are examined by numerical experiments of a few flow models, and proved to be useful for both uniform and non-uniform computational meshes of the finite difference equations.
