Dese GNU Archimedes will be added to the OpenSourceTCAD?
Thank you for your contribution to the OpenSourceTCAD
I have to say, TCAD is a very samll area.

It seems to be very limited (mostly 2D only it seems) from my point of view, so I don't want to invest time into it at the moment. But I would happily accept a pull-request for it.
