air under hull, alpha.water=1 threshold pressure

laurent98 · June 26, 2014, 23:43

hi all,
after running LTSInterFoam to a planning hull, (high speed catamaran) there is air bubble under hull, which is not realist. with Finemarine from numeca i fix that problem by setting alpha to 1 if the pressure is above a threshold.
did anyone implement this option in a solver?
thank by advance for answering
Laurent

hi,
here a Z_view of the air under hull problem.
i would be very happy to find a solution at this behavior....
i'd like a code where i can say:
if pressure > 800 then alpha.water=1
i am a beginner in C++, is this goal very complicate???
thanks you for helping Laurent

Hi Laurent,

I will not answer you but ask you if you can help me with the streaking under hull with Finemarine, I posted a thread today to have some new ideas to avoid streaking with fine marine. Could you said more about your experience or perhaps I can contact you by email?

Thanks
