Apply a force to the whole mesh motion
 

Hi everyone.
I am currently working with a moving domain two-phase flow (interFoam).



I am prescribing the motion through linearMotion, but throughout the simulation I change the value of the velocity in order to simulate my movement.

The issue is that the movement is not smooth when in transition. I know I could use a prescribed motion with a tabulated6DOFMotion, but it becomes quite cumbersome to do so.


That's why, I was wondering if it was possible to consider my whole domain as a solid, and apply a force (that I would vary) through time in order to prescribe a motion?


If there is any example of such application, It would be great!

Thanks

Any updates on this topic??
