4. Setup (Physics)

Duplicate Steady Flow Project

First, complete the Steady Flow Past a Cylinder Tutorial. In the Workbench Project Page of your steady flow project, (Right Click) Solution > Duplicate

Launch Fluent.

(Double Click) Setup in the duplicate project. Select Double Precision. Then click OK

Transient

In this step here we will, tell FLUENT to solve for the unsteady flow. As you can see, by default FLUENT will solve for the steady flow.

Problem Setup > General. Set Time to Transient.

Specify Material Properties

Problem Setup > Materials > Fluid > Create/Edit.... Set the viscosity to 8.333*10^-3 kg/m*s. Click Change/Create then click close
