I have been running a surface
 

I have been running a surface piercing foil in rasInterFoam. The free surface forms correctly early in the simulation, but over time it looks like there is a reflection off the outlet patch that does not seem correct.

A tar'd copy of the case files is here and a small movie showing the wave height contours plotted on the gamma = 0.5 iso-surface is here .

If someone could review the movie and case files and point me in the right direction I would appreciate it.
