Importing the Mesh

Create a sub-directory for the tutorial called pipe. Copy the file containing the problem geometry and mesh data (mixing_pipe.ccm) supplied with the STAR-CCM+ installation into this directory. Users wishing to generate this mesh from scratch should complete Tutorial 1.1 and Tutorial 1.2 of the STAR-CD Meshing Tutorials volume.

Start up STAR-CCM+ in a manner that is appropriate to your working environment and select the New Simulation option from the menu bar.

STAR-CCM+ will create an additional tabbed window for the new simulation in the Explorer pane and give it the default name Star 1. Import the supplied mesh file into the simulation:

Select File > Import from the menu bar

Navigate to the pipe directory created previously and select file mixing_pipe.ccm

Click the Open button to start the import. The Import Mesh Options dialog will appear. Select the following options:

Run mesh diagnostics after import

Ensure that the Open geometry scene after import and the Don't show this dialog during import options are not selected and then click OK.

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). At the end of the import process, it will also create an initial (default) simulation tree in the Star 1 window.

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.

The tutorial continues with Checking the Mesh.
