电驱NVH自动仿真插件开发1——JMAG与ABAQUS联合二次开发

基于JMAG二次开发API，开发插件Create_case.py与NVH foece to abaqus.py提高电磁仿真和后处理效率。

Create_case.py用于自动创建仿真电流边界、求解设置、计算工况。

NVH foece to abaqus.py用于自动读取JMAG电磁数据导出到文本文件中。

基于Abaqus二次开发API，开发Motor_NVH插件，用于自动创建电驱频响有限元模型，该插件自动将JMAG输出的时域数据转换成频域载荷谱，并完成有限远模型的求解与边界设置，极大提高了电驱振动仿真的效率。

部分JMAG插件代码如下：

defCreate_case(study,file,poles):

defmain_create_case(study):

ifret==1:
