Abstract

The invention discloses a topological mesh generation method and an electronic device based on boundary constraints. The method comprises: according to the load condition of a geometric component to be analyzed and the geometric characteristic of the geometric component, the boundary of the geometric component is constrained, and a discrete node about the constraint is set; connecting the discretenodes and meshing to obtain an initial discrete triangular mesh; as for that initial discrete triangular mesh, an optimized triangular mesh is obtain by utilizing a topological mesh optimization method and a metric tensor and optimize the initial discrete triangular mesh by an iterative method based on a boundary constraint condition. The invention makes the process of mesh division and optimization very simple, fast and accurate, and only needs to restrict the boundary to generate a triangular mesh satisfying the calculation precision and saving the calculation resources.

Description

technical field [0001] The invention relates to the technical field related to computational mechanics, in particular to a boundary constraint-based topological grid generation method and electronic equipment. Background technique [0002] Computational mechanics has played a huge role in the continuous development of high-end industrial design. To put it simply, computational mechanics is to convert the components that need to be studied and calculated into discrete continuous units by using grids, and then use mathematical models and physical models to simulate the corresponding results through computer calculations to provide reference for designers. in accordance with. Computational mechanics is being developed and applied more and more because of its high efficiency, accuracy, resource saving and other characteristics. However, many factors determine the accuracy and efficiency of calculation, among which discrete grid is an important factor. [0003] The scale of th...
