Some modifications before running the simulation

I need to change a few things to get useful data for the simulations. First I need to set the timestep taken to fixed interval, which is a simple change of one function call. I also plan on investigating using velocity of mass centers instead of velocity of angles. I also want to try and and a pause or save ability that allows the simulation to stop and save its progress so it can be continued later on. That way simulation progress can be saved at regular intervals. I also need the allow the simulation to run to equilibrium as apposed to running until a predetermined time. I also need to make sure I have properly configured my simulation to utilize my GPU as well as my CPU.

I believe I might need to utilize more powerful computers than my own. If anyone knows anything about getting access to more powerful computers at RPI please let me know.
