Hello,

I have carried out a multiphase simulation of water/air using VOF.
I'm interested in knowing the height of the interface between the water/air. How could I do it?

Firstly you have to define, what is considered to be an "interface height" - If you will plot two-phase interface by 2 contours, you will obtain an accurate contour with NO height of interface. When you choose more contours when plotting, you can deduct some height of interface however, where this starts and ends? At contour of 1%, 5%, 10% portion of the second phase? You must be the one to determine. It seems to be easily found out from the picture attached.

hi
i must have 2 color in my simulation,red for water and blue for air,but i have more color between red and blue, and i dont determine water depth,how can solve this problem?

In countours, set No. of levels to 2.
