 March 19, 2012, 05:25 How to plot the wave contour in ship flow (free surface) problem #1 New Member   deddy chrismianto Join Date: Mar 2012 Posts: 3 Rep Power: 7 Hi, I have some problems to display my results in wave contour on the ship flow (free surface). I have already used isosurface method but beside that, I want to know wave contour based on z/Lpp. Please give me some tips to make it. thank you

Then you can plot this variable on your isosurface of the water surface or any other plot you care to do.
