The Finite Element Method Be Used In Electromagnetic Field Analysis

Eletromagnetic fields is an important branch of Electromagnetics.The methods that are used to analysis Electromagnetics fields has always been a measure of the degree of Electromagnetics'development.Form the 18th Century,Faraday as the first person delimited field.By now,electromagnetic fieds has been quantization. Electromagnetics is an important role.because electromagnetic fields are invisibility and very easy be effected by boundary condition,it is difficult to analyze.The traditional mothod is only used in teaching.The Finite Element that is a very important numerical mothed has been widely used to analyze difficult fields in project.The purpose of this paper is using ANSYS software to solve the problem of electromagnetic fields.Because ANSYS software have a powerfui graphics,it can be used to draw the picture of electromagnetic fields.Firstly,vector analysis was used to get the basic properties of electromagnetic fields.Secondiy,comparative analysis of the four major methods,it is easy find that the finite element analysis is a advantege method in electromagnetic fields analysis.Finally,by using the finite element software-ANSYS software,it is foung that ANASYS software is accuracy and convenience compared with the traditional analysis methods.it also shows the basic methods and techniques that is about to how use ANSYS software.
