Problems solved by technology

[0004] However, the latest version of CAE pre-processing software such as finite element processors (HyperMesh or ANSA) does not have an automatic classification method for meshes around holes. If engineers want to deal with mesh quality, they can only manually select some important parts for processing. Some simple classification, or re-grid, time-consuming and labor-intensive, the effect is poor
At the same time, manual inspection is prone to omissions, errors and other problems, resulting in poor model quality, low analysis accuracy, and affecting the final result of simulation analysis

Abstract

The invention provides a hole periphery grid classification method and device. The method comprises steps of all two-dimensional grids in a computer aided engineering (CAE) model being acquired; for each two-dimensional grid in all the two-dimensional grids, obtaining all holes in the two-dimensional grids, and marking the holes; for each marked hole, obtaining the classification reference information of the hole; and according to the classification reference information, determining the types of the grids around the holes, so the classification reference information of all the holes in the two-dimensional grids is obtained based on all the two-dimensional grids in the CAE model, and according to the classification reference information, the types of the grids around the holes are determined, and thereby automation of classification of the grids around the holes in the CAE model is realized; the method is used for quickly counting a plurality of defects of grids around holes caused bygeometrical shapes, grid division sizes, grid division methods and the like, the simulation analysis efficiency is greatly improved, and errors caused by manual operation are avoided.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a grid classification method, device and storage medium around holes. Background technique [0002] As an interdisciplinary numerical simulation technology, Computer Aided Engineering (CAE) has attracted more and more attention from the scientific and engineering circles, and it has been widely used in the research and development of automobiles. At present, in In the automotive product development process, CAE has become an extremely important and indispensable link. [0003] At present, when using finite element software to perform CAE analysis pre-processing on automotive structural parts, the parts are generally processed into a two-dimensional grid, and the quality of the grid around the hole is focused on. Triangular elements and inconsistencies in the surrounding grid will directly lead to stress concentration around the hole, and the situation that the stress...
