I am not sure about the mesh input formats for NEC, but there are some
very good solid modellers/meshers around - most should be able to import
something that Autocad exports. Have a look at FEMAP, for example.
(http://www.femap.com) This can export mesh information in a "neutral"
format, from which its very easy to create mesh information for other
analysis codes. The parallel hybrid MM/PO/UTD software (FEKO) imports
FEMAP neutral files directly. (http://www.feko.co.za)
