Summary
This paper describes a novel approach to generating a multi-block decomposition of 2-D domains into high quality quad sub-regions using the medial axis transform (MAT). BuninĂ­s continuum theory for unstructured mesh generation [1] is used as a means of understanding how the information contained in the MAT can be used to find effective positions for mesh dislocations.
