Traditionally, adaptive mesh refinement of HF frequency domain solvers, based on a tetrahedral grid, does not improve on the initial, facetted representation of the structure. The originally created tetrahedra are just divided further where necessary. Here the mesh adaptation will converge, not to the results (e.g. S-parameters) of the actual structure, but to those of the initial, segmented model.
