If it is possible.
Suppose I have a cube which center is placed at the mean water level. How would I go about extracting how much of the cube is "touched" by water, especially if it was to undergo rotations etc.?
did you find a way to get what you looked for?
I used the volume method on paraview as you told on another thread.
Where you able to get number of wetted area for quantitative purpose?
Look at the volume parameter, when it touches water it changes value, compared to when it does not.
Then you need to do a lot of tedious math, but then it should be good enough.
