I had to inflate the "Super Fast Battlecruiser" design to work with Springsharp
I am very interested in the Springsharp program, especially since I also have a program (although mine is not in the public domain, at this point). I just tried to make my alternate "Super Fast Battlecruiser" design work with Springsharp. I guess I am happy that something like what I would have liked to have is possible at all:
