[求助]线圈参数优化的问题

tang76

附件所示的模型，单击运行，能跑完第一个扫描点，但在后面的运行中会提示：
[error] Matrix 'Matrix1': 'Current1' is an invalid source for matrix setup

请问我的模型哪里建立或设置得有问题？

谢谢！

perch88

你先别优化呢，看看parametric analysis可以否

tang76

多谢版主回复，我其实就是想利用parametric analysis来实现参数扫描。这个参数是Cylinder1自定义材料的电导率，最终想给出Matrix随电导率变化的情况。

谢谢

tang76

现在的情况是，第一个电导率计算能通过（当然不排除模型建立得有问题而获得错误的结果），后面就出现上面所说的错误。

谢谢

tang76

这是整个运行过程的输出信息，烦请大侠帮我分析一下模型哪里出问题了。
谢谢

进一步试验发现，如果删除那个Matrix1，参数扫描能进行下去，可这个Matrix1是怎么设置错了呢？望高手再帮我看看是什么问题。

谢谢

perch88

matrix里面算的是什么？

tang76

两个线圈的电感矩阵

perch88

这个模型有问题，最外面包的不是空气
什么分析都不行的

tang76

非常感谢版主的回复。你说的是不是外面少了个region?
刚才我在外面加了，还是不行。

谢谢！
