I'm not sure Optistruct (and another FEA softs like Ansys, Abaqus,...) can do contact analyse at microscopic level.
Ansys do this type of analysis. Abaqus as well ...
For Ansys, please see the following paper : https://www.researchgate.net/publication/237566348_Methods_for_Generating_Rough_Surfaces_in_ANSYS
What's your goal? Why you need this simulation?
