Algorithm of conforming triangular meshes on contact surfaces
接触面的一致性三角形网格生成算法*

In order to simplify the contact problem of multi-body in the field of numerical simulation, this paper designed an algorithm of conforming the triangular meshes on contact surfaces, which contained five basic processes: built the adjacency topology relation of meshes, searched the overlapped meshes, amended the overlapped meshes, copied meshes and repaired the interspaces. The method of searching overlapped meshes oriented node pairs, adopting node-projection and searching holes based on edge-circles improve the accuracy of contact zone detection, and the method of three-axis blocking sorting improved the efficiency. The examples show that the algorithm is accurate and efficient.
