I am a first-year grad student researching polyurea polymers and am working with some MD simulations of the polymers. I am fairly inexperienced with MD and am hoping someone could point me in the direction of some literature or even just some personal experience that might detail the accuracy of these simulations to an angstrom standpoint. We are hoping to use our MD data to back up some changes in SAXS/WAXS data but need to be sure the simulations are actually precise. One potential area of concern is that our MD simulations are just on the hard segment of the polymer, negating the soft segment. I am unsure whether this will affect the results enough to impact them to a significant degree. Any information would be greatly appreciated, thanks!
