Contours

The Pressure and velocity contours obtained from the results of the baseline case and the optimized case are compared.

Note: The baseline case is simulated with only flow module added, assigning fluid properties, boundary and volume conditions and the result file is saved as 2D_shape_optimization_model_baseline.sres in the working directory.

The steps to create contours are:

1. Click Load Results in the Simulation Panel.
2. Select the required result file in the ensuing Load Results dialog box, click Open.

 

Pressure Contours

1. Select annulus from the Volumes in the Geometric Entities Panel.
2. Select Pressure from the Variables list under Variable drop-down list in the Results Panel (see, Figure 9.36). For variables and legends, refer Post-Processing.
3. In the Properties Panel, navigate to View Tab, select Y from the Mirror dropdown under Global Parameters. It offers to mirror the displayed contour in the selected plane.
4. Enter Drag Coefficient = {cd%4f} under Text Label in Global Parameters of View Tab.
5. Enter Front under Text Label in Global Parameters of View Tab.
6. Enter Rear under Text Label in Global Parameters of View Tab.
7. Enter Front Normalised Length = {fl%1f} under Text Label in Global Parameters of View Tab.
8. Enter Rear Normalised Length = {rl%1f} under Text Label in Global Parameters of View Tab.
9. Enter Front Angle = {ftheta_new%1f} [degree] under Text Label in Global Parameters of View Tab.
10. Enter Rear Angle = {rtheta_new%1f} [degree] under Text Label in Global Parameters of View Tab.
11. Select all CAD Surfaces, enable Outline in the Results Panel.
12. Below is the comparison of pressure between Baseline case and Optimized case (See, Figure 9.36 and Figure 9.37).

Velocity Contours

1. Select annulus from the Volumes in the Geometric Entities Panel.
2. Select Velocity Magnitude from the Variables list under Variable drop-down list in the Results Panel see, Figure 9.38. For variables and legends, refer Post-Processing.
3. Refer to the Pressure Contour, on how to add Text labels to the Display Panel, as shown in the Figure 9.38.
