Automated two-dimensional multi-block meshing using the medial object

Abstract

This paper describes the automatic generation of a structured-dominant mesh based on an automatic block decomposition obtained using the medial object. The mesh generator will produce a mesh for an arbitrary two-dimensional geometry, where quadrilateral-dominant or triangular meshing is used when structured meshing fails. The domain is automatically partitioned into blocks (sub-regions), and an appropriate meshing algorithm for meshing each block is then automatically selected. It will also generate conformal interfaces or hanging interfaces between adjacent blocks as required.
