电磁场数值分析方法讨论

Discussion on numerical analysis methods of electromagnetic field

阐述了求解工程电磁场几种数值计算方法的原理及其共性与区别．作为特例，对同一磁场分布，用不同计算方法进行了求解，并对结果作了分析讨论．结果表明：只要采用适当的前处理技术，各种数值分析方法具有相同的计算精度．

The principle of some types of numerical adulation method solving engineering elec tromagnetic field and their common characters and distinctions have been discussed.As a special case,the same magnetic field diStribution has been solved using different caicula.tion methods and the numerical results have ben analysed and discussed.Its shown that each numerical calculation method has the same calculating accuracy as long as suitable pre-processing technique has been employed.
