II. The bath

 

 

The idea is to simulate the filling of a bath. To do this, we used the following model.
 




This case is more a two phase flow than a change of phase. Thus, to simulate this case, we used the VOF model, and tried all the schemes given...
 

The results obtained, when there were results, have never been satisfying. The main problem was that the water input was magically stopped  at the middle of the bath, and so was disappearing at this level.
Moreover, the outlet conditions imposed were pressure conditions and seemed to be inefficient, because the air was not going out of the "bath". So, it was decided to force air to leave the box by placing a flow outlet having the same rate than the inlet. But, no result were found furthermore.
So, if you are interested...
