 March 8, 2013, 05:16 problem with the filling of a bottle #1 Member   Join Date: Mar 2013 Posts: 92 Rep Power: 5 hi, i tried to solve the tutorial proposed by Hassan Hemida that concern the filling of a bottle ("Free surface tutorial using interFoam and rasInterFoam", Hassan Hemida, 2008). the problem is that in the tutorial proposed by Hemida the chamber of water is always full while in my case i have this situation only as initial condition. the water infact move from chamber to bottle and the chamber remain empty. I follow all the instruction of the tutorials but i think that there is something of wrong in the boundary condition http://www.google.it/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CEEQ FjAB&url=http%3A%2F%2Fwww.tfd.chalmers.se%2F~hani% 2Fkurser%2FOS_CFD_2007%2FHassanHemida%2FHassan_Hem ida_VOF.pdf&ei=uas5UaGYN4bdswax94HwDg&usg=AFQjCNES IhuTSpfZOFPx4XZb950QQyZ21g&sig2=uzpQQ4rYCbeH6bo_u3 LT9w&bvm=bv.43287494,d.bGE thanks for the help

hello giack,

I face the absolutely same problem. Could You solve it?
I changed the inlet boundary condition of alpha.water from
Quote:
 p { margin-bottom: 0.25cm; line-height: 120%; } inlet { type fixedValue; value uniform 1; }
to
Quote:
 p { margin-bottom: 0.25cm; line-height: 120%; } { type inletOutlet; inletValue uniform 1; value uniform 1; }
The result is, that the solver continues, but too much air flows in.
Thanks for help

I changed the BC for p_rgh field for the inlet to: Code: ```inlet { type prghPressure; rhoName rho; p uniform 0; value uniform 0; }``` this helped to get better results although I think too much water is flowing in compared to the results from the tutorial of Hassan Hemida. Any suggestions? Kind regards
