Compute Expression between different solutions?

Hi

Does anybody know if there is a way to compute an expression using two or more different solutions?

For example if I do a parametric scan of a waveguide geometry and I would like how similar the electric field is, I could compute the overlap between the fields of a different solutions, which would read something like this:

Int ( E1x*conj(E2x) , dA)
where E1x the x component of the electric field of solution 1 and E2x the electric field of solution 2 is, the product is then integrated over the 2d plane of the solution.

Thanks a lot!
Niklas

Hi

if its from the same data set check the at() and with() operators in the doc, these should help

Good luck
