MESHING WITH THE TRIMMING METHOD	Chapter 4
Trimming the 3D Template to the Geometry

Trimming the 3D Template to the Geometry

The final stage in the Trimming process is to cut the 3D template to the geometry surface. Trimming produces a discretised representation of the internal engine volume. At this stage, you will also perform some quality checks, merge small edges to improve cell connectivity and add an extrusion layer to the wall boundaries.

To cut the template to the geometry surface:

• In the Select panel, click Trimming

•In the Trim panel, click Cut to begin trimming the template

•The Child output panel displays the process output and any error messages from the trimmer

•es-ice automatically separates the different regions of the model before trimming them

•Once trimming is finished, click Status to display information about the trimmed regions. Included in the output is the number of cells for each separate region.

The next step is to verify that the correct vertices are stored in Template VSet 10.

•In the Trim panel, check that the Cylinder option is selected

•Click Get to load the cylinder part of the mesh into the Template window, and put Template VSet 10 into the currently active vertex set

•In the Plot Tool, activate the Fill toggle button, click CPlot, and manipulate the view to display the cylinder mesh as shown in Figure 4-30
