Introduction
This is a 3-D simulation using a mesh with pre-set boundary conditions. The geometry is a chute with a polyhedral mesh topology, and features internal walls and multiple inlets. The user imports the mesh into Azore, prepares solution monitors, runs the simulation, and then post-processes and analyzes the results.
What You'll Need
Several demonstration CFD models are included in the Azore installation files. The files needed for this tutorial are located in the directory AzoreCFD-Documents-->Azore-Tutorials-->3D-Polychute-Full. Please note this tutorial requires participants to have a license or free trial of Azore Advanced or Premier.
Step 1: Launch Azore
Launch Azore from the desktop icon and explore the menu options.
Step 2: Import the Mesh
Navigate to File→Import to import the mesh file, polychute.cas from the Azore file directory.
Step 3: Prepare Solution Monitors
Select Database→Solution Monitors→Point to set up 2 point monitors, one in the near side chute and one in the inside center pipe. The coordinates of the near side chute point are (2.58, 0.4, 6.14) and the coordinates for the inside center pipe point are (-0.14, 0.26, 9.5).
Select Database→Solution Monitors→Surface to set 2 surface monitors, at the inlet and outlet. For each monitor, click the surfaces button to assign the appropriate surface. For the inlet, choose to monitor the Area Weighted Static Pressure. For the outlet, monitor the Normal Velocity RMS.
Step 4: Run and Monitor the Simulation
Save the database prior to initiating the run. Choose File→Start Run to begin a run, and specify the run to continue for 500 iterations. Once the run process begins, use the Display→Monitors→Residuals menu to display the residuals. Selecting Display→Monitors→Show All Monitors will display the point monitors. Under the same menu, navigate to Add Monitor→Properties in order to select the two surface monitors for the near side chute and the center pipe. To stop a run prior to 500 iterations, navigate to File→Stop Run.
Step 5: Analyze Results
Once the data is loaded for post-processing, select the Contours tab and highlight the surface z=6.20526-2ftabove in the Post list. Press the generate button to display the data for this surface. Change the field to display the Z Velocity data for this surface and check the Display Range box. The display units can be modified by pressing the Units button.
To display pathlines, select the Paths tab, press the Initialize Paths button, and highlight shut-inlet under the Flow list. Press Generate if necessary. To see additional pathlines, deselect the Distribute box. The color settings can be changed from Color By Specified to Color By Field. Clicking the Stats button will display pathline statistics in the Log Messages Area.
Navigate to the Reporting→Surface Data to calculate surface data. Select a surface (z=6.20526-2ftabove) and choose Standard Statistics from the dropdown menu. The solution statistics will be reported in the Log Messages Area.
Step 6: Export Surface Data
To export surface data from Azore, choose File→Export. Select surfaces and the data type to export. The VTK format can be used in Paraview. Indicate a folder where the exported data will be stored.
