Hi everybody,

ive a simulation with two phases, air and water.
In the simulation water is running down a slanted plate for 2 sec.
The RMS Mass(Air) and RMS Mass(Water) history are ok (below 10e-4).
The Imbalance for Air is also ok, but for water the history is ocsillating around 7.5%.

My questing is:
What is the difference between RMS and Imbalance?
Maybe someone could give me an example to understand this issue.

Greetings
Mat
