Press the Results button in the Workflow to extract information from the simulation that was done. 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. For many cases, the default setting for these vector plots use a vector appearance that is too big so they overlap making it difficult to analyze.
Select the velocity vectorVector to edit the setting in settings with which the vectors are defined. Press the plane 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 locationLocation. Retain Symbol distribution as Uniformly distributed and input a value between 2000-4000 for Approximate number of points. Change the Symbol Sizing sizing in the Appearance section to 0.35 in order to alter the size of the vectors, and change the Symbol length to Constant. Press the play 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 see.
To plot the pressure changefield, create a contour on the side of the flow volume. Select contour 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 TotalPressureTotal Pressure.
The same thing can be done to plot the velocity change field as a contour. Repeat the steps above to create the contour Contour, but make the variable Velocity Magnitude instead of TotalPressureTotal Pressure.
