Free surface plot
 

Hello everybody. I have a little problem. I made a transient simulation of water flowing trough a pipe that was full of air at the beginning. In post processing I use an isosurface of water volume fraction (value=0.5) to see what's happening. I'm seeing the interface, but I'm not seeing the water because I don't see the interface between water and pipe. How could I do to see the water flowing and not only the interface (air-water)? Thanks in advance. Bye.

Isovolume

But with isovolume you get the volumes thta have a water volume fraction of 0.5 and that is only the interface again.

Make a plot of the superficial velocity

Thanks. but on a isosurface, with vectors or how specifically? THANKS AGAIN FOR YOUR HELP.

Isovolue, Mode: Above Value

Sorry.I saw it after answering you. Thanks and bye.
