新手如何学习COMSOL电磁场仿真

jaylee0816

本想根据一个例子改一改就行了，结果一改就出现了错误“求解模型发现未定义的值
- Detail: Undefined value found in the stiffness matrix.
There are 842 equations giving NaN/Inf in the matrix rows for the variable mod1.Aphi
at coordinates: (0.00462941,0.00998296), (0.00469055,0.00996227), (0.00475,0.00993301), (0.00480416,0.00989685), (0.00485355,0.00985355), ...
and similarly for the degrees of freedom, NaN/Inf in the matrix columns”，根本不知怎么解决，软件的很多参数也不知道怎么设置，想问一问各位大侠，非物理专业的人如何学习COMSOL呀？

最好是看懂一个例子，然后再改，我当初学3.5a时候是根据model guide里面一步一步的重复例子，然后再尝试着去弄懂每一步的目的，然后再去改
