Select PISO from the Pressure-Velocity Coupling drop-down list.

Info
title

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.

 
 For Step 1 through Step 3, please refer to Steps in Steady Flow Past a Cylinder.
