Running the Polyhedral Volume Mesher

The polyhedral and prism layer meshers can now be run:

As before, the output from the meshers will be shown in the Output window and status updated in the status bar. When the process is complete, the message Reordering faces in region Region 1... done will be shown in the Output window. A summary of the mesh quality criteria (namely, the cell quality, face validity, skewness angle and volume ratio) for the core and prism meshes can be viewed by scrolling the Output window display up.

To view the volume mesh representation, do the following:

The scene will be updated to show the polyhedral volume mesh with prismatic near wall layers:

A close up of the prism layer mesh (with thinner thickness) is shown below:

The properties of the volume mesh can be seen by selecting the Representations>Volume Mesh>Finite Volume Regions>Region 1 node.

This completes the volume meshing part of the exercise. You may now proceed to export the mesh, run an analysis of the mesh or jump to the part of the tutorial that explains how to replace the imported surface mesh with a modified version and produce a new mesh with one button press. You can also proceed to re-mesh the geometry using trimmed cells with prism layers. Be sure to save the simulation file first if you want to keep the results of this meshing session - a suggested simulation name is control_valve1.sim.
