Simulate the velocity-dependent shear stress

Hi everyone,

I'd like to simulate the velocity-dependent shear stress between two surfaces.

Each surface moves in opposite directions at constant velocity, like in this article : M. Chandross, G. Grest, M. Stevens, Langmuir 18 (2002) 8392–8399.

How can I achieve the caliculation using Materials Studio?

Regards
