Hi Rob,

The external excitation acceleration that I am applying is continuous over time and is not changing magnitude. It is being applied as a body force vertically over the whole domain, however the volume fraction contours show the free surface setting down as the time goes on.

I did run the simulation for some more additional time to see what happens beyond 0.5 seconds and we can see that the magnitude is dropping which is not according to what the paper has published. Something seems to be damping the body force and settling the free surface which shouldnt be the case since the excitation I am applying is steady continuous and not an impulse or a ramped force.

Any ideas would be greatly appreciated!
