Abstract

The embodiment of the invention discloses a finite element grid automatic division method, equipment and storage medium. Wherein, the method includes: obtaining the three-dimensional geometric features of the target parts from CAE software; according to the characteristics of the three-dimensional geometric features, determining the features that need to be cleaned and cleaning; using the CAE software to perform grid generation on the cleaned three-dimensional geometric features, The three-dimensional grid features are obtained; according to the classification of the three-dimensional geometric features, the three-dimensional grid features corresponding to each category are adjusted; and the adjusted three-dimensional grid features are corrected according to the grid quality requirements. This embodiment realizes the automatic finite element grid division process and improves the grid division efficiency.

Description

technical field [0001] Embodiments of the present invention relate to finite element mesh processing technologies, and in particular, to an automatic finite element mesh division method, device, and storage medium. Background technique [0002] In the development process of automobile body structure, CAE performance simulation is an indispensable link, and finite element meshing is a key factor affecting the simulation results. At present, there are professional pre-processing tools for meshing, such as Hypermesh from Altair and ANSA from BETA, 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, and manually identify or adjust each link of mesh division, so that the final finite element mesh can be more in line with the requirements of CAE performance simulation. This process is very time-consuming, require...
