Abstract

The embodiment of the invention discloses a finite element grid automatic division method and device and a storage medium. The method comprises the following steps: acquiring three-dimensional geometrical characteristics of a target part from CAE software; according to the characteristics of the three-dimensional geometric features, determining features needing to be cleaned and cleaning the features; performing grid generation on the cleaned three-dimensional geometric features by using CAE software to obtain three-dimensional grid features; according to the classification of the three-dimensional geometric features, adjusting the three-dimensional grid features corresponding to each classification; and according to the grid quality requirement, correcting the adjusted three-dimensional grid characteristics. According to the embodiment of the invention, an automatic finite element grid division process is realized, and the grid division efficiency is improved.

Description

technical field [0001] The embodiment of the present invention relates to a finite element grid processing technology, and in particular to an automatic finite element grid division method, device and storage medium. Background technique [0002] In the process of automobile body structure development, CAE performance simulation is an indispensable link, and finite element mesh division is a key factor affecting the simulation results. At present, there are professional pre-processing tools for meshing, such as Altair's Hypermesh and BETA's ANSA, both of which include one-dimensional, two-dimensional, and three-dimensional meshing algorithms. [0003] However, in the existing automobile development process, it is still necessary to manually operate software tools to manually identify or adjust each link of mesh division, so that the final finite element mesh can better meet the requirements of CAE performance simulation. This process is very time-consuming, requiring more m...
