Summary
Mesh matching is an effective way to convert the non-conforming interfaces between two hexahedral meshes into conforming ones, which is very important for achieving high quality finite element analysis. However, the existing mesh matching algorithm is not robust and efficient enough. In this paper, the algorithm is improved in three aspects: by introducing a more precise criteria for chord matching and the concept of partition chord set, complex interfaces with internal loops can be handled more efficiently; by putting forward a mesh quality evaluation method, the sheet extraction operation during mesh matching is sped up; by bringing up a new solution, self-intersecting sheet can be inflated locally. Test results demonstrate the effectiveness of the improved mesh matching algorithm.
