ansoft15中瞬态场2D斜槽分析报错，求大神指点

瞬态场中做2D分段斜槽分析，网格为静态场计算后导入的自适应网格，参数化扫描后运行到N=1（N从0到9）时开始报错，错误如下：

这种错误的原因是为什么？我一直想不明白，求大神指点

大神今天在睡觉啊

岁月如割

这估计的有道翻译一下

看大神没来，我说说我的计算过程，我是做2D斜槽分析，网格导入的是静态场自适应网格，用瞬态场算，给我提示说两个模型不一致，这是为什么？瞬态场导静态场网格这个没问题，但做斜槽分析就不行？谁给点拨点拨？非要手动划分网格才能做参数化扫描？导入的就不行么？

在线接着等

本人做斜槽的时候扫描没问题，但是气隙磁密的数据只保存了最后一个点，不懂为什么！

刚开始试用这个新版本，一直都用12版本来着。

看你回复就知道你默认的网格划分

很多好东东啊

maxwell 2D 做斜槽分析？不可以的吧

网格划分我是根据默认的数据再减小一倍的。

这中做法有依据么？以什么判断网格划分质量，我看能多同学都是用的一种划分

当然可以，问题就处在能不能做负载分析，我指的是永磁电机

只能说网格单元细化能提高精确度，至于怎样细化，这个我也是参考论坛上的。

同学，你的气隙划分多少层呢？

3层，多少层还有讲究？最终目的还不是为了把气隙的网格加密，上面的问题找到了，斜槽分析还是有讲究的
