Abstract
A simple refining algorithm is proposed for general block-structured meshes. The method converts a multi-dimensional problem of mesh-refinement to a set of one-dimensional problem of length-measurement (or similar geometrical operations). A successive-over-relaxation (SOR) operation can be applied to accelerate convergence. The method is robust, easy to implement, and provides nearly uniform spacing between mesh surfaces.
