Can some one advise me?

I'm trying to solve the case of transient, incompressible, turbulent flow with convection and species transport (water vapour into air). I'm also using the dynamic mesh model on a part of one of the boundary. The problem is that I'm getting very high values of negative gage pressure in some parts of the domain. The gage pressure can attain a least value equal to negative of the operating pressue. But I'm getting considerably higher values. Also since I'm using a pressure boundary condition on two of the boundaries therefore the value of the pressure in the domian is not arbitrary. Can someone give me an advice for the solution?
