hull foils high Fr Free Surface problems with LTSInterFoam
 
2 Attachment(s)
Dear all,
i try to run simulation with OF 2.2.1 LTSInterFoam at 6 or 12m/s and i get two problems:
-some bad little waves all around
-a very high velocity in air, where this object is.
any idea or directions to make thinks better will be very appreciate!
thanks be advance.

Hi again,
part of solution, was to reduce cAlpha to 0.5, no more little wave, but no more ventilation to!
what solver, (interFoam, cavitatingFoam ...) specialist would subject to predict the ventilation of a free surface piercing foil???
thanks for helping
