alpha becomes bigger than 1 in interFoam
 
Dear FOAMers
I have a problem with interFoam. I am simulating a 2-D channel with 1 inlet and 1 outlet. alpha is 1 at inlet. When I use fixed velocity at inlet every thing is OK but when I change the BC at inlet to fixed pressure the alpha becomes bigger and bigger. (bigger than 1)
What is the problem? Could any one help me?
Any help will be appreciated
Best regards
