Results

Press the Results button in the Workflow to extract information from the simulation. In order to find information that can be readily used, press Evaluate Results. Once the evaluation is complete, AIM will automatically output a vector in the Results section under Objects.

Select the Vector to edit the settings with which the vectors are defined. Press the Plane button in the top right corner of the model window; this will create a plane in which we can plot the vectors in two dimensions. Select the plane as the Location. Retain Symbol distribution as Uniformly distributed and input a value between 2000-4000 for Approximate number of points. Change the Symbol sizing in the Appearance section to 0.35, and change the Symbol length to Constant. Press the Play animation button in the model window to see how these velocity vectors develop over time.

A zoomed in view of below the backwards facing step shows the recirculation phenomenon that was expected.

To plot the pressure field, create a contour on the plane that you created earlier. Return to the Physics task, select Contour in the Add drop down menu, choose the plane to map the contour onto, and assign the Variable to be Total Pressure.

The same thing can be done to plot the velocity field as a contour. Repeat the steps above to create the Contour, but make the variable Velocity Magnitude instead of Total Pressure.
