Three-dimensional automatic local remeshing for two or more hybrid meshes

摘要

In this paper, an automatic local remeshing method is proposed for merging two or more hybrid meshes consisting of prisms, hexahedra, pyramids and tetrahedra to reduce users' efforts and turnaround time for mesh generation as an extension of the local remeshing method for small devices by Ito et al. (AIAA J. 2009; 47(5): 1270-1276. DOI: 10.2514/1.40875). Two types of relationships between two volume meshes are considered: (1) a volume mesh containing the other smaller volume mesh inside (parent-child relationship) and (2) a volume mesh connecting to the other volume mesh (sibling relationship). The primary advantage of the proposed method over the existing ones is that it can handle the geometries in the two hybrid meshes intersecting each other. Two examples are shown to demonstrate the local remeshing method.
