| Electromagnetic compatibility analysis and forecast based method of moments inthe current system is widely used in electromagnetic analysis, the method is consideredto be an effective method of numerical analysis. This paper is the use of C and C++language for electromagnetic compatibility of the Communication Vehicle System ofsimulation software pre-processing of the triangulation grid technology research onVisual C++6.0and OpenGL platform.The task group software to surface mode built the initial model, according to theRWG vector basis function moment method can be divided into triangular meshes. Themain work of this paper is to(1) opposite vertices do not mesh vertex of initial model preprocessing, made avertical line triangulation algorithm to form vertex in vertex triangulation model;(2) for the body surface mesh model, used a three-point advancing front triangleDivision method of propulsion method with constraint conditions, continuous anddiscontinuous in curvature, broken down by different scale grid;(3) At the antenna surface contact with the body, respectively using polygontriangle decomposition and difference subdivision method, comparing the two methods,in order to achieve line contact point triangulated surface mesh of good quality;(4) Pre-split design model and triangulated mesh output interface, enablingresearch group of papers made by modules and software integration.In this paper, triangulation mesh method for low-frequency to high frequencychanges, for surface curvature continuous and discontinuous, for line and planeconnections. Through extensive simulation study, using the triangulation mesh methodcarved out of mesh with uniform, fine, algorithm is stable, and reliable. |
