Automatic Hybrid Mesh Generation For The
Boundary Face Method
Author(s)

Abstract
A new hybrid mesh generation method is proposed and applied to generate mesh
for three-dimensional solids with open-ended tubular holes. Regions around the
tubular holes are represented by hexahedral elements, and tetrahedral elements
tessellate the rest of the domain. The procedure consists of three steps. Firstly,
surfaces of tubular holes are recognized and discretized, and then the hexahedral
mesh is generated by a sweep method. Finally, the Delaunay tetrahedral mesh
generation method coupled with the advancing front method is applied to
generate tetrahedral mesh. By the proposed method, high-quality hybrid mesh
for solids with small tubular holes can be automatically created. And the number
of the obtained elements is far less than the traditional tetrahedral mesh. Several
examples are presented to demonstrate the robustness and efficiency of our
method.
Keywords: hybrid mesh, sweeping, Delaunay method, advancing front method.
