Sounds very tough. If you have an idea of how to go about the model building,
NAB can help you turn ideas into a real program. But it doesn't arbitrarily
solve problems by itself.
You might want to just put in H-bonds you want to form as "NMR" constraints,
then run some annealing protocol with the two molecules to get them to come
together, perhaps also restraining the RNA hairpin to not move far from its
starting position. But that's just one idea.
