Abaqus couple temperature displacement analysis: Bimetallic Strip: Step by Step 

Are the energy/ power units consistent? Would it be mJ (and mW) for Tonne, N, mm, s? 1J = kg*m^2/s *1000g/kg*1000^2mm^2/m^2 --> factor of 1000^3 from J using Tonne, N, mm, s? Or am I missing something?

It should be mJ rather than J for energy in this unit system.

why selecting static step for interference? What if selecting coupled temp-displacement step for interference? Any differences?
