ansoftv12 3D仿真磁密矢量为什么有Z方向分量正确吗？

yangdongz

用V11分析需用2天时间，结果非常理想，与实际相差不大

楼主ENZO：
  你若用V12分析后可检查直流线圈的磁链曲线发现ψ＞32WB,用V11只有7WB左右，ψ=B*S*W
B（极芯）==约1.8， S（极芯）=45*45*PI=6400，W=650，

Z方向的分量是由于mesh和求解误差引起的，V11和V12求解时剖分肯定不一样．

自个顶一下，望版主回复

很难啊，我学不会啊

等待后续结论

用V12把爪极电机的问题算了一下， 没有改变模型设置， 结果见图片。  请YANGDONGZ把V11算出来的结果贴上来做个比较。

两个版本做出来不一样？

B的向量图是对的吗

这样看B向量是不对呀~

ENZO

第一个B向量图是转子部分的， 第二个是定子的， 因为两个在一起看不清楚。  哪位做过V11的分析可以上个图看看有什么分别。

现在上传V11计算的结果

用V12计算的结果：注意直流线圈的FLUX曲线数值相差很大

用12.1打開錯誤很多

太高深了，有点看不懂

Z方向的分量是由于mesh和求解误差引起的
