Robert, Wow, that's an oldie! I wasn't aware that you could get support for this product anymore? The last time I used Greenfield you were only allowed a maximum of 9 conductors, and arbitrary shapes are out of the question. It's not a bad piece of software, but my opinion is that you can find a more practical software for your work in the 21st century. Actually, the software that was recently posted on this list from the Mayo Clinic works very well and it's FREE. I stuck a microstrip and stripline into it and generated the exact same results (within a tenth of a unit) that I obtained using a common 21st century tool - Ansoft. Here is a link to that software in case you are interested... http://sourceforge.net/projects/mmtl/ There is a pretty cool iteration tool included to "dial-in" your impedance.

The main product name is Omega PLUS, with sub-modules called EZ Greenfield 2D, PCB Greenfield, etc. Just looking for general impressions and experiences.
