Reply To: Why FDE Eigen mode solver is giving different solution than Comsol FEM solver?

It is hard to believe the dimension can be shrinking in FDE solver. Please check the original dimension and use the ruler on the left panel to roughly measure the size. From your screencopy, the rectangle has x-span roughly 70um, and center y span (about the diameter) about 7um including the rectangle y-span.
