Setting Up Data Export to Create Animation

We would like to create an animation of the vorticity magnitude after the solution has been calculated. To do so, we will need to export data from FLUENT to CFD-Post, the post processor used to view results. To do so, go to {_}Solution > Calculation Activities > Execute Commands > Create/Edit. Now, set up the window to appear as the image below. The command entered is 'file export-to-cfd-post unsteady-%t.cdat x-velocity y-velocity velocity-curl q no no'. In this case, we will export the x and y components as well as the curl of the velocity every time step.

Advance Solution in Time

Solution > Run Calculation. Set Time Step Size to 0.2 seconds and set the Number Of Time Steps to 200. Now, click Calculate. (You may have to hit Calculate twice.) Now, have a cup of coffee. Continue the time-stepping until you get sinusoidal variation in the lift coefficient.
