Your "dissertation" (do you get a PhD for that?) however is doomed
Now don't you think that is a bit harsh? The guy is just asking for help and advice and you say that!?
JayLane07, I would assume that for a dissertation the basic info you have found would go a long way to helping. If it's anything like my universities flight simulator, the modelling won't be the most technical ever. I guess it would be more important to analyse the results instead of getting a super accurate model.
Anyway, I'm doing my dissertation now as well and funnily enough may be using a simulator at my university, but not quite as much as you seem to be planning. Have you seen what data the simulator model needs??
Anyway, good luck and no, your dissertation is NOT doomed.
