Moving Blimp Sim

Hi everybody,

I am following this tutorial on ansys site and below is the youtube address for it.

This sim is related to the stationary ship. My question is how I should modify for moving ships.

I have a small engine that has 1 kg of thrust. How and where should I enter this value?

p.s. I am a total noob in ansys (specially fluent)

Currently I haven't explore the addition to thrust addition in a CFD simulation, must probably going to be a transient simulations.
If the velocity of the blimp is constant you can add the boundary condition in the front of the blimp and outlet in the back, and other BC is either opening or wall (ground?). I don't know for the buoyancy can be in a same simulations or not.
