To view the CFD analysis results:

1. Click mouse button 3 on the job named fluid-cfd, and select Results from the menu that appears.

   The output database file fluid-cfd.odb opens in the Visualization module.

2. Create pressure and velocity contour plots.

   1. In the toolbox, click the View Cut tool to activate a view cut.

   2. Click the View Cut Manager icon .

   3. In the View Cut Manager, select the Z-Plane.

      Abaqus/CAE creates a view cut of the fluid domain showing the interior.

   4. From the Views toolbar, select the front view.

   5. In the toolbox, click to create a contour plot.

   6. From the main menu bar, select ResultField Output. In the Field Output dialog box, select PRESSURE as the output variable and click OK.

   7. In the toolbox, click to open the Common Plot Options dialog box. Toggle on Feature edges for the visible edges, and click OK.

      Abaqus/CAE hides the mesh feature lines in the model.

   8. In the toolbox, click to open the Contour Plot Options dialog box. Toggle on Continuous under Contour Intervals, and click Apply.

      Abaqus/CAE creates a smooth pressure contour plot, as shown in Figure E–15.

      Figure E–15 Pressure contour plot.

      

   9. Using the Field Output toolbar, select V as the output variable to plot.

      A contour plot of the velocity magnitude appears, as shown in Figure E–16.

      Figure E–16 Velocity magnitude contour plot.

      

   10. In the toolbox, click to create a time history animation. Select an output variable (velocity, pressure, etc.) to animate the results.

3. Plot the turbulence variables.

   1. Using the Field Output toolbar, select TURBNU as the output variable.

      Abaqus/CAE displays a smooth contour plot of turbulent viscosity, as shown in Figure E–17.

      Figure E–17 Turbulent viscosity contour plot.

      

   2. Toggle off the view cut by clicking the View cut tool .

   3. From the Views toolbar, select the isometric view.

   4. Using the Field Output toolbar, select YPLUS as the output variable.

      Abaqus/CAE creates a smooth contour plot of nondimensional wall distance on the wall surface, as shown in Figure E–18.

      Figure E–18 YPLUS contour plot.

      

4. Verify the mass balance.

   1. Select ToolsXY DataCreate.

   2. In the Create XY Data dialog box that appears, select ODB history output as the source, and click Continue.

   3. In the History Output dialog box, select the MASSFLOW output at the inlet and outlet and click Plot, as shown in Figure E–19.

      Figure E–19 Mass flow rates at inlet and outlet.

      

   4. In the History Output dialog box, click Save As.

   5. In the Save XY Data As dialog box, select sum as the Save Operation, name the new X–Y data object mass-balance, and click OK.

      Abaqus/CAE creates a plot representing the sum of mass flow rates at the inlet and the outlet surfaces, as shown in Figure E–20. The plot verifies that inlet and outlet mass flow rates are balanced.

      Figure E–20 Sum of mass flow rates.
