Step 5: Solve!
Set the solution controls
Main Menu > Solve > Controls > Solution... 
Select PISO from the Pressure-Velocity Coupling drop-down list.
PISO allows the use of higher time step size without affecting the stability of the solution. Hence it is recommended pressure-velocity coupling for solving transient applications.
Uncheck Skewnes-Neighbor Coupling.
