Chiara Modenese proposed the following answer:
Hi,

Just a small comment on what you want to achieve rather than how. I
agree with Bruno saying that kinetic energy alone (however small in
absolute value) will not tell you if your test is quasi-static. You need
to compare the total kinetic energy with the elastic potential energy of
your system and make sure that the former is a small fraction of the
latter (that is to say that dynamic forces are always present but their
effect is negligible). How small a fraction you will need to determine
until the solution becomes insensitive to the walls' velocity (or strain
rate). Alternatively you can also look at the unbalanced ratio.
