Hi, There is a code called Meep, I believe from MIT and it does many of the things that you are interested in. I was aware of it in a different life about ten years ago. It has always been built on Linux so you should be good. There is a mailing list (look below) and am sure you can get more information. Please note, that I am responding quickly and have not checked as to present status and availability. this is the best information that I have. good luck.
