Maxwell Equations in Half Dimensions

[Kyle Stephens]

I am trying to solve Maxwell's Equs. in 2.5D, but my problem formulation seems to be off as the problem object isn't square. I tried adding tau terms to the problem but that didn't help either. Can anyone help? I attached the file to this post, any help would be greatly appreciated.

Hi Kyle,

You need to add Lagrange multipliers and tau terms to enforce the solenoidal constraints and boundary conditions. For the system to be square, you need the same number (and dimensionality) of equations as variables going into the problem.  See the gauge conditions and tau method pages in the docs for more info.

Best,
