These are the field solvers that had what I understood to be a libre
license from Clemson's list.  There are fourteen packages here that
made the cut and align with the goals of this project.  I have no
familiarity nor expertise with any of them or I would be in a better
position to make a recommendation.  It would be useful to be able to
model not only the differential microstrip structure with ground
shield traces and vias, but also signal vias for tuning them to
transparency.
