Solution/Results

Press the Results button in the Workflow to extract information from the simulation. In order to calculate the solution and find information that can be readily used, first press Evaluate Results. Once the evaluation is complete, AIM will automatically output a Vector in the Results section under Objects. The vectors show air velocity.

Select the Vector to edit the settings with which it is defined. Change the Approximate number of points to 1000 to increase the density of vectors in the display, then change the Symbol length to Constant to make the smaller vectors easier to see. Press the Play button in the model window to see how these velocity vectors develop over time.

To find the total pressure on the walls of the duct, return to the Results task and select Contour from the Add dropdown menu. Select all of the outside faces of the flow volume (except the inlet and outlet) and change the Variable to Total Pressure. This will plot the pressure on the duct walls.

A temperature contour can be added by using the same process, but instead selecting Temperature as the Variable.

Streamlines are also an excellent way of visualizing the flow and are easily created in the Results section of the Workflow. Right click in an empty space of the model window and select Add > Results > Streamline. Change the Seed location to Inlet 1 and change the Approximate number of points to 100. Finally, press Evaluate to calculate and display the streamlines. A creative way of seeing how the streamline behaves over time is to change the appearance of it to show different things. For example, the line type can be changed in order to show how the streamlines rotate in response to the flow. Change the Line type to Ribbon and increase the Ribbon width to 2 or 3. Press the Play button in the model window to see how these streamlines develop over time.
