waterlevel [m] from VOF
Hi, has anyone tried to export the waterlevel [m] from a transient result file?
the model: I set up a simple rectangular wavetank (L,H,W=115,5,3). It`s a two phase model with water and air. The free surface is calculated using VOF. On one side a piston wavemaker (moving wall) produces waves. the aim: I would like to export the waterlevel (Z) at a given bottom point (X,Y) for every timestep to get a timedependend waterlevel plot. A little tip would be great, thanks so far Jan |
Re: waterlevel [m] from VOF
You are looking for a Free Surface Simulaton (Tutorial 7: Flow over a bump). You have to write out the VolumeFraction at every timestep.

Re: waterlevel [m] from VOF
The way I do it is to define an isosurface at VOF = 0.5. Then create a poly line along the side you want (I can only get side not point)
I then create an expression, the average height at that polyline, and then plot that against time. This is the best I have found to track free surface height |
