A METHOD OF TRIANGLE MESH GAP CLASSIFICATION AND MENDING
As a result of the complexity of the ship structure analysis models, the logical relationship of the model data is frequently lost in the transformation between the design and analysis software. The holes, slots and small curved surfaces caused by the failure of transformation will create mesh gap in the model, causing calculation divergence. Meshing of the ship model by universal finite element mesh (FEM)software shows that the number of gaps is comparatively small in relation to triangle and each gap group consists of only a few nodes. The paper proposes one new method using adjacency matrix to group gaps found in whole FEM analysis model, create mesh gap adjacency matrix by connected weight, class the gaps according to connectivity,and then regroup connected components by articulation nodes. BFS algorithm and marked array are applied to adjacency matrix traversing while mending triangle methods are provided. The results show that it is more effective and better for meshing complicated models.
