What kind of simulations do you want me to make for you? As in, mainly, what Kind of star system?
I know pretty much everyone here can make all the single-star solar systems you can think of, but binaries? Trinaries? Quadruple systems? Haven't seen many people do that before, other than myself, so, I will at least try to make whatever multiple-star systems you ask for, although depending on complexity, I may or may not be able to make a stable system, but "simple" circumbinary systems I can do. All you need to say is the approximate mass of the two center stars, and extra stars for trinaries and quadruple star systems, how many planets, and the types of planets you want, if you want habitable ones, (if so how many??)and, if you really want it that much in-detail, you can tell me the names of the planets and stars (within acceptable parameters...). Now on the quadruple star systems...the only successful one I have made was where the system was very, very lopsided in mass, as it was two stars larger than the sun orbited by a binary of a red and brown dwarf, so that is the only kind I know how to make, though I can still try to make less lopsided ones, but I cannot guarantee that I will be able to make a stable system.
List away with all the parameters you want, but it will make it harder for me and a larger chance I won't be able to make the system exactly the way you want it.
