Lifting simulation for a CubeSat. Linear Dynamic/Base Excitation or Static/Gravity Force?

I'm trying to simulate the launch of  CubeSat which is essentially a lifting simulation.

Now I am having trouble as to which force to use.


One option is using Linear Dynamic->Base Excitation Force.

Second option is using Static->Gravity Force.


In this paper (page 68),_Power,_and_Thermal_Subsyst…  Option 1 is used.

The second option would be the more logical option I'm guessing though.


I've ran the simulation using both methods and I get very similar but slightly different results. Which force should I use to best simulate static loads acting on the CubeSat during launch.
