  Hi everyone !
  
  I am making the simulation to solve the problem as illustrated in the picture to study about the oscillation of the rigid body before it get equilibrium condition
  
  I am wondering which module in Ansys should use to solve it.
  
  It would be grateful if you give me a recommendation
  
  Thank you very much.

  I recommend you edit the post and change the category to Fluid Dynamics. You will want to use either Fluent or CFX to model this.

  I simplified this model by simulation a rigid body is free-falling by gravity and under bottom face is subjected to a air pressure. I have tried but not successful in fluent
  
  I think it should be use some kind of system coupling. Is it right?
