Development of high-precision alignment technology for automatic reusable mesh generation

Abstract

We proposed an advanced mesh generation technique that reuses the proven analysis models by similar sub-part search. The proven CAD data and corresponding mesh data are managed as analysis know-how, and sub-parts similar to CAD data of analysis know-how is searched for a newly designed CAD. Then, by reusing the mesh data of the similar sub-parts, the technique for generating an analysis model with the same quality as the proven data was developed. However, in the process of arranging the mesh data of the similar sub-part, the position shift may occur depending on the pattern of the similar sub-part shape. Therefore, we developed a calculation method for the coordinate transformation matrix that minimizes the amount of misalignment regardless of the shape pattern, and confirmed that misalignment does not occur.
