Dynamic display method of complex curve electromagnetic wave vector based on support point fitting

Abstract

The present invention discloses a complex curve electromagnetic wave vector dynamic display method based on support point fitting, including the following sub-steps: S1. Read the point list of the complex curve model from the nastran grid file [P] N Concatenate list with points to form list of line elements [Seg] M ; S2. Based on the fitting of support points, the fitting function of the three-dimensional three-dimensional curve in space is obtained; S3. According to the number of sampling points S of the curve set by the user n +1 for uniform sampling of complex curve models; S4. Computing curves at each sampling point P i (x i ,y i ,z i ) on the unit tangent vector and then computed with t i Two orthogonal unit vectors that are perpendicular to each other and S5. Construct a sheet with dimension S n The +1×18 data table is used as the data structure format for the dynamic display of electromagnetic waves; S6. Realize the dynamic display of complex curve electromagnetic wave vectors according to the data table. The invention considers the coupling between orthogonal fields, and can dynamically display the wave coupling of electromagnetic waves.

Description

technical field [0001] The invention relates to the field of electromagnetic waves, in particular to a method for dynamically displaying complex curve electromagnetic wave vectors based on support point fitting. Background technique [0002] In the field of electromagnetic waves, in order to effectively observe electromagnetic waves, it is often necessary to visualize the curved electromagnetic wave vector. The traditional field vector visualization only considers the case of a single direction vector field, and does not consider the coupling between orthogonal fields; Dynamically display the fluctuation coupling of the electromagnetic wave; currently there is no data structure format suitable for the dynamic display of the electromagnetic wave, which brings a lot of inconvenience to the dynamic display of the electromagnetic wave of the load curve. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to ...
