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！

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

烦请高手帮我看一下，对高手来说设置参数扫描应该是很简单的事情，可我这个新手就是怎么也搞不定

多谢了

虽然线圈的感抗等参数，与其上所加源没有什么关系，但是软件中计算感抗矩阵，是通过能量法，也就是说你所求线圈上必须要有电流流通，个人感觉你模型中current1强制为零是不对的，应该给一个电流值。

tang76

非常感谢版主的回复，这个强制加0电流是为了模拟断路，参考：
Maxwell 2D Application Note A 2D Eddy Current Problem


多谢

刚才试了把另一个线圈的电流也改成1 A，还是同样的错误。

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
