Hi, well I guess it depends on what models you mean... REMD is a technique to enhance the conformational sampling. So if you have a e.g. a protein that is disordered or has large disordered parts. Using REMD several copies of the same system are simulated, each replica at a different temperature. Then, each replica can explore a different portion of the conformational space: the higher temperature replicas are able to move between different regions of the potential energy surface without staying in any of them, while the lowest temperature replicas can get trapped in local minima and are able to accurately explore the regions of the potential energy surface. This way you can obtain more information about conformational space then by simple MD.
