For 1) I think I will define just a monitor of phase located in the top to know if is gas or liquid and determine after the distance based on the time step. For 2) I though to define a line on the radial direction as after extract the volume fraction vs height. I wonder if can be a more "automatic" option to determine the height of the liquid thickness?. Or which other options do you recommend. I hope I made myself clear.
