(Double Click) Setup in the Workbench Project Page.
Select Double Precision.
If you are using a computer that has more than one core, it is advantageous to turn on the parallel processing feature of FLUENT. This feature will divide the solution domain amongst the number of cores that you specify. The maximum number of cores that you can specify is 4 for the standard FLUENT package. The Swanson Lab at Cornell University has dual core machines. In order to use both cores, set Processing Options to Parallel (Local Machine) and set the Number of Processes to 2. These selections are shown below.
If you have more cores set Number of Processes to the number of cores you have ( 4 is the limit). Now, when you run your calculations in FLUENT you will have more than one core working for you, which will significantly reduce your computation time.
(Click) Mesh > Info > Size
You should now have an output in the command pane stating that there are 18,432 cells.
(Click) Mesh > Check
You should see no errors in the command pane.
Problem Setup > Materials > Fluid > Create/Edit....
Then set the Density to 1 kg/m^3 and set Viscosity to 0.05 kg/m*s. Click Change/Create then click Close.
Problem Setup > Boundary Conditions > farfield1.
Set Type to velocity-inlet. Click Edit.... Set Velocity Specification Method to Components, set X-Velocity to 1 m/s, and set Y-Velocity to 0 m/s.
Problem Setup > Boundary Conditions > farfield2..
Set Type to pressure-outlet.
Problem Setup > Boundary Conditions > cylinderwall.
Set Type to wall.
Problem Setup > Reference Values.
Set the Density to 1 kg/m^3. The other default values will work for the purposes of this simulation.
