Abstract

The invention discloses a dynamic three-dimensional display method of electromagnetic waves suitable for complex curved surfaces, comprising the following steps: S1. Reading the point list of the complex curved surface model from the nastran grid file [P] N Join list with points to form list of triangle surfels [Tri] M ; Among them, N is the number of points, M is the number of triangles, initialize a data table [Tbl] whose dimension is N×8 N,8 ; S2. Calculate point coordinates and unit normal vectors for each surface element in the surface element list, and accordingly to the data table [Tbl] N,8 Filling; S3. To the filled data table [Tbl] N,8 Process each line of data in and complete the arrangement of visualized data; S4. Perform dynamic visualization processing on the electromagnetic waves on the complex curved surface to realize the dynamic three-dimensional display of electromagnetic waves. The invention can realize the fast and slow effects of electromagnetic fluctuations, the fluctuation amplitude, and the adjustment of electromagnetic fluctuations forward and backward with time, and avoid the problem that the peak or trough reverses due to the connection sequence of points in different grid models.

Description

Technical field [0001] The present invention relates to the field of electromagnetic field calculations, in particular to a dynamic three-dimensional display method of electromagnetic waves suitable for complex surface surfaces. Background [0002] In the field of electromagnetic field calculation, for the electromagnetic wave propagation of complex surface surfaces, it is often necessary to dynamically display, but the two-dimensional visualization of electromagnetic waves on the traditional surface of complex surfaces cannot reflect the three-dimensional vibration characteristics of elastic waves; although the visualization of traditional planar electromagnetic waves is a three-dimensional effect, it cannot be applied to non-planar complex surfaces; at the same time, in the existing dynamic display scheme of electromagnetic waves, the point connection sequence in different mesh models leads to peaks or troughs reversing. This brings many inconveniences to the dynamic three-dim...
