show the profile of free surface
 

hi everyone
i have used VOF to simulate the transport of free surface, now, i want to know the profile of the free surface, how can i get the details about the profile of the surface.such as the height of surface relative to a plane.
thanks for your help:)·

create an isosurface of VOF(1) = 0.5 and then plot the z coordinate of the isosurface. depending on what you are interested on you might add an intermediate step of making an isosurface of the isosurface where the x or y coordinate is constant.

thank you very much for yours.:p
