| description | This paper proposes an advanced mesh generation technique that reuses the proven analysis models by similar sub-part search. The purpose of this development is to reduce interactive mesh improvement work time and to comply with the mesh specifications. The number of product specifications is increasing due to global business development and diversification of needs. Hence, the execution frequency of simulation is increasing. Therefore, it is necessary to reduce the working hours. Furthermore, quality improvement and standardization of analysis models are required because the general designers have learned to manage V&V. This technique consists of two distinctive techniques. First, it is the technique to search the sub-parts from newly design CAD where have similar shape with the archived feature sub-parts contained in the proven CAD models. In this technique, the similar sub-parts are retrieved from a CAD model described by boundary representation and made correspondence relation surface pairs of a retrieval model (proven model) and a target model (CAD of new design). A similarity score is based on the attributed graphs of a retrieval model and a target model. And, this score is calculated by a geometrical similarity and topological similarity. Second, mesh can be generated automatically by arranging and merging the mesh of similar sub-parts. Experimental results show that this technique can efficiency achieve mesh generation without interactive mesh improvement operation. |
