If so you can create a surface plane on the ships hull, and then insert a new contour at that location (the surface plane you created) and colour the contour by volume fraction of water or air.

 August 22, 2013, 02:15 hi #3 New Member   mohammad Join Date: May 2013 Posts: 10 Rep Power: 6 thank you becouse of your answer but I don't want see the countur.Iwant to make a wave profile charts on my ship hull in order to see the differences between experimental tests and cfd.my analysis contain air and water .thank u

Also post a picture of your domain and setup. You haven't told us what you're doing, and unfortunately we can't read your mind, so you have to tell us!

Then generate a contour plot on that plane of volume fraction. Make sure you generate a contour at VF=0.5. Next create a polyline using the VF=0.5 contour. Finally, plot the polyline height in CFD-Post, or export it and plot it in your choice of package (excel, tecplot, matlab, whatever).
