The only place I know that has black hole programs that you can use fairly easily is Clifford Pickover's book Black Holes: A Traveler's Guide. In the back of the book there's a big list-but they're all in computer code. So if you know computer languages, look it up. Otherwise, forget it. I'd e-mail them to you, but I don't have a scanner and I'm too busy to type them all onto my computer. Sorry.
