Tom, I thought that you supported an infinite plane model.

Have you considered that it might be a cut-away?

Have you considered that a cut-away should be labeled as such? Have you considered that finite edge is required for the MLOF to flow over and that your infinite FE model wouldn't have that? Have you considered answering questions explicitly? By the way, you can now choose: 1) finite FE with a reasonable, but grossly inaccurate, explanation for the compass dip or 2) infinite FE as your hero demands, without any hope of explaining the compass dip.

Don't worry about choosing as far as everyone here is concerned since RE is the better model in either case.
