free surface level
 

Hello,

I am modeling a fluid going into and exiting a drop box with a free surface model. Of interest to me is the height of the fluid in the box, especially near the walls, because I want to prevent erosion (the fluid is a slurry, being roughly estimated right now as a pseudo-fluid). Basically I want to figure out what the height of fluid is that is slamming into the walls (changes with time, I know) so that I can make the box bigger.

How could I get paraFoam to give me the height of the fluid from the bottom of the box? I'd imagine I'd have to pick a point or a line and model it against time, but I don't know how. Please help.
