Overflow error
 

آHello every one !
I am trying to model a two phase channel including water and air. I specify the velocity of water and air as the inlet boundary condition and average static pressure equal to zero for the outlet. The analysis type is transient. 100 kpa pressure and slight velocity are considered as initial condition. But every time that I run this code, program stops by overflow error. Who can help me ?

Are you sure your exit boundary is correct? Check the flow over a bump tutorial for how they do it.
