Abstract

The invention discloses a method and a device for generating a structural grid. The generation method of the structured grid includes: obtaining the initial height of the grid and the growth rate of the grid; when the initial height of the grid is less than the preset height, and the growth rate of the grid is less than the preset growth rate, the grid is adjusted according to the partial differential equation The initial height of the grid and the growth rate of the grid are processed to obtain the first structured grid, wherein the first structured grid includes the first number of grid nodes; the node information extracted from the first number of grid nodes conforms to the preset Conditional target grid node information; generating a second structured grid according to the target grid node information, wherein the second structured grid includes less than the first number of grid nodes. Through the present invention, the effect of reducing the limitation of grid generation is achieved.

Description

technical field [0001] The present invention relates to the field of structured grids, in particular to a method and device for generating structured grids. Background technique [0002] At present, when generating structural grids, because the structural grids generated by partial differential equations are absolutely orthogonal, the grids are smooth and uniform, and have good adaptability to irregular boundaries, partial differential equations can be used to generate structural grids. However, there are obvious shortcomings in the structural grid generated by partial differential equations. For example, the solution of partial differential equations has divergence and convergence. When generating grids for irregular boundaries, the grid generation divergence often occurs. As a result, mesh generation fails. To ensure the success rate of grid generation, the initial height of the grid and the growth rate of the grid must be very small to ensure the convergence of the grid ...
