Problems solved by technology

But this greedy algorithm has many defects
First of all, only one sample point can be added at a time; secondly, when searching for the next sample point, it is necessary to search on all boundary points, which takes a lot of time

Embodiment Construction

[0027] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The data sample simplification scheme of the present invention is to first use a group of cuboids to group the boundary grid points, each group has about 100 grid points, and calculate the average position and average deformation of each group of grid points. When searching for the next group of sample points, first search out the 3-5 groups with the largest deformation error of the average position of the grid points in each group, and then search for the grid points in these 3-5 groups Search one by one to determine the grid point with the largest grid deformation error in each group, and add it to the sample space as a new sample point.

[0029] A sample reduction method for radial basis function support points, comprising the following steps:

[0030] Step 1. Collect boundary grid point coordinate...

Abstract

The invention belongs to the technical field of structured grids, structured / non-structured mixed grids and dynamic grids of point clouds, and in particular relates to a method for simplifying samples of radial basis function support points. The data sample simplification scheme of the present invention is to first use a group of cuboids to group the boundary grid points, each group has about 100 grid points, and calculate the average position and average deformation of each group of grid points. When searching for the next group of sample points, first search out the 3-5 groups with the largest deformation error of the average position of the grid points in each group, and then search for the grid points in these 3-5 groups Search one by one to determine the grid point with the largest grid deformation error in each group, and add it to the sample space as a new sample point. The time for searching sample points can be reduced by adopting the technical scheme of the invention.

Description

technical field [0001] The invention belongs to the technical field of structured grids, structured / non-structured mixed grids and dynamic grids of point clouds, and in particular relates to a method for simplifying samples of radial basis function support points. Background technique [0002] Dynamic mesh technology is widely used in aerodynamic shape optimization design, unsteady flow simulation and aeroelasticity simulation. Efficient moving mesh technology is one of the key technologies to solve such problems, and it is also the most important technical "bottleneck" in realizing engineering applications. Mesh deformation technology is a kind of dynamic mesh technology, which is widely used in engineering. [0003] At present, mesh deformation technology is generally divided into structured mesh deformation technology and structured / unstructured hybrid mesh deformation technology. Commonly used structural grid deformation techniques include: over-limit interpolation gri...
