Step 10: Postprocessing

1.   Inspect the solution at the final time step.

(a)   Inspect the contours of static pressure in the valve (Figure  13.5).

Graphics and Animations Contours Set Up...

  The negative absolute pressure indicates cavitating flow.

For details about the cavitation model, see this section in the separate Theory Guide.

(b)   Inspect the velocity vectors near the point where the valve meets the seat valve (Figure  13.6).

2.   You can also inspect the solution at different intermediate time steps.

(a)   Read the corresponding case and data files (e.g., valve_tran-0.010000.cas.gz and valve_tran-0.010000.dat.gz).

(b)   Display the desired contours and vectors.

3.   Play the animation of the pressure contours.

Graphics and Animations Solution Animation Playback Set Up...

(a)   Select pressure from the Sequences list.

  The playback control buttons will become active.

(b)   Set the slider bar above Replay Speed about halfway in between Slow and Fast.

(c)   Retain the default settings in the rest of the dialog box and click the button.

For additional information on animating the solution, see Tutorial  4 and see this section in the separate User's Guide.

4.   Play the animation of the velocity vectors.
