Once you click at the second point, the Please Select Displayer dialog will appear. Click the (Create Planar Section) button in the toolbar and then define the plane by clicking on the two end-points of a straight line passing approximately through the center of the large inlet pipe at one end, and the center of the outlet pipe at the other end. We will now inspect the interior mesh structure by creating a cross-sectional plane that bisects the geometry. Verify that no malformed or irregular cells are present on the mesh surface. Examine the mesh more closely by holding and dragging the left mouse button to rotate it the right button to pan it the middle button to zoom in and out and produce a Graphics window display such as the one shown below: Open the Scenes node, followed by the Geometry Scene 1 node In the Displayers node, select the Geometry 1 node In the Properties window, tick the Mesh checkbox. The Graphics window will initially show all parts of the mesh as solid, colored surfaces. This will create a new node, Geometry Scene 1, in the simulation tree. Right-click on the Scenes node and select New Scene > Geometry.

The tutorial continues with Checking the Mesh.Ī simple but effective method of checking the mesh is to display it on screen and examine it visually. To create a file for the simulation and give it a proper name: Select File > Save from the menu bar Type mixing_pipe in the File Name text box then click Save Note that the title of the simulation window also changes to mixing_pipe. At the end of the import process, it will also create an initial (default) simulation tree in the Star 1 window. STAR-CCM+ will give a summary of all data imported from this file in the Output window (for example, that the mesh contains 82,339 cells). Select the following options: Run mesh diagnostics after importĮnsure that the Open geometry scene after import and the Dont show this dialog during import options are not selected and then click OK. The Import Mesh Options dialog will appear. Import the supplied mesh file into the simulation: Select File > Import from the menu bar Navigate to the pipe directory created previously and select filemixing_mĬlick the Open button to start the import. STAR-CCM+ will create an additional tabbed window for the new simulation in the Explorer pane and give it the default name Star 1. Start up STAR-CCM+ in a manner that is appropriate to your working environment and select the New Simulation option from the menu bar. Users wishing to generate this mesh from scratch should complete Tutorial 1.1 and Tutorial 1.2 of the STAR-CD Meshing Tutorials volume. Copy the file containing the problem geometry and mesh data (mixing_m) supplied with the STAR-CCM+ installation into this directory. ObjectivesThe tutorial gives a detailed account of how to: Initiate a STAR-CCM+ session that builds a CFD model for a simple problem Specify turbulence and physical property models Specify fluid properties Apply boundary conditions Perform a CFD analysis using one of the STAR-CCM+ solversĮvaluate the solution results by creating simple vector and contour plots Produce plots of particle tracks Combine particle tracks with vector or contour plots The tutorial starts with Importing the Mesh.Ĭreate a sub-directory for the tutorial called pipe. The tutorials Objectives are outlined in the next section. Adiabatic and no-slip conditions are assumed at the pipe walls.

These properties vary throughout the pipe as the two streams mix. The air stream entering the solution domain at each inlet has a specified velocity, temperature, turbulence intensity and turbulence length scale. There is also an outlet pipe on the right-hand side through which the fluid exits.

The assembly has two inlet pipes, located on the left and center of the above figure, through which air at different temperatures flows into the interior.
