Importing the Sector Geometry Spline

You start the simulation setup from a 2D geometry spline in .csv format.

To launch Simcenter STAR-CCM+ In-cylinder:
  1. Start a double-precision version of Simcenter STAR-CCM+ and create a new simulation by clicking File > New.
  2. In the Create a File dialog, select an appropriate parallel option and set Compute Processes to at least 4.
    For information on the parallel options, see Process Options.
  3. Click OK.
  4. From the Simcenter STAR-CCM+ toolbar, click (Open Simcenter STAR-CCM+ In-Cylinder).
    A Simcenter STAR-CCM+ In-cylinder tab opens within Simcenter STAR-CCM+.
  5. Select File > Save As... and save the simulation under the name DieselEngineSectorModel.sim.
  6. Import the 2D spline:
    1. Right-click the Geometry node and select Import 2D Curve.
    2. In the Open dialog, set Imported 2D Section Type to Head and Piston Bowl (At BDC).
    3. Navigate to the inCylinder folder of the downloaded tutorial files and select sector2DCurve.csv.
    4. Click Open.
      The 2D curve is imported and defines the 2D Section.
  7. In the Graphics window, position the section to obtain a view similar to the one shown below.


  8. Save the simulation .
