FEMA 3D是一个以有限元法为基础的电磁铁数值计算三维软件包。该软件包适用于多种电磁铁三维恒定磁场、三维涡流场、三维永久磁铁磁场及各种电器电磁系统吸力特性的计算。软件包由数据前处理(网格自动剖分及图形显示);磁场计算(三维矢量位法和等参元双标量位法)及电磁铁吸力特性计算;数据后处理等三部分组成。其中网格及场图等可以绘于屏幕由打印机打印输出,形象直观。
FEMA 3D is a three-dimensional software package for numerical calculations of electromagnets based on finite element method. The package is suitable for the calculation of a variety of electromagnet three-dimensional constant magnetic field, three-dimensional eddy current field, three-dimensional permanent magnet magnetic field and suction characteristics of various electrical and electromagnetic systems. Software package consists of data preprocessing (automatic meshing and graphical display); magnetic field calculation (three-dimensional vector bit method and isoparametric double-scalar method) and electromagnet suction characteristics calculation; data post-processing and other three parts. Mesh and field maps, etc. which can be painted on the screen by the printer print output, visual image.
