- I always get amused by comments such as this. FEA is merely the establishment of
- a set of trial functions which are valid over a specific region in the domain
- (rather than the total domain), and which are typically constructed in such a
- way that the valid domain need not be rectilinear. As such, virtually every
- numerical method is a subset of FEA (I admit to some issues with Boundary
- Element Methods). I am unsure of the details of your transmission line method,
- but the implications are that it is a specific class of FEA. I would be
- interested in more comments (and I will dredge up the journal article!).
