Which mesoscale module will be suitable to study thin film of polymers on solid surface?

Hallo everybody,

                     I am going to start a new work with thin polymeric films. My objective is to check the dewetting of polymeric films on different metal surfaces using mesoscale modules. It seems that I can either use DPD or coarse graining MD approach.

  Can anyone please suggest which route will be more suitable for this kind of study. Remember that metal surface and polymer interactions are important in this case.

Thanks for your attention.
