  Hello,
  
  I want to apply acceleration to the smaller cube and see the surface stress distribution of the larger cube. However, I found that I can only set a global acceleration, which is the same as standard gravity. How can I achieve this? Thank you in advance, and I appreciate any replies!

  Set the material density of the larger cube to 0 then the inertial forces created by the acceleration load, which acts on all bodies, will be zero on the larger cube, but will be non zero on the smaller cube that has a non zero material density.
