For incompressible flow, the energy equation is decoupled from the continuity and momentum equations. We need to solve the energy equation only if we are interested in determining the temperature distribution. We will not deal with temperature in this example. So leave the Energy Equation set to off and click Cancel to exit the menu.

Define Governing Equations
Problem Setup > Models > Energy
Use the default and click OK.
Problem Setup > Models > Viscous
Select Laminar under Model and click Edit.
We want to leave the default value so you can click Cancel.
Problem Setup > Materials
Double click air or select it and click Create/Edit. Make sure air is selected under Fluid Materials. Set Density to 1.00 and Viscosity to 1e-4 so that we can get Re of 1e4.

Click Change/Create.
Define Boundary conditions
Problem Setup > Boundary Conditions
Set the inlet boundary type to velocity-inlet. Then click Set...Set the velocity magnitude to 1 m/s. Set the outlet type to pressure-outlet boundary. Use gauge pressure of 0 Pa.Use the default value of wall for the center line. Set the far field to symmetry boundary type. Symmetry boundary condition means that the component normal to the wall is zero.
Problem Setup > Boundary Conditions
> Operating Conditions
Use the default value. Click OK.
