To convert part of your domain to polyhedral cells, go to the
Convert Skewed Cells panel
GridPolyhedraConvert Skewed Cells...
Figure 6.7.7: The
Convert Skewed Cells Panel
Select the zone(s) you want to consider for local polyhedra conversion under
Cell Zones. Once the zone selection is made, the
Current Maximum Cell Skewness and
Cells Above Target (%) skewness are displayed.
Target Maximum Cell Skewness (see Section
6.7.2) and click the
Cells Above Target (%) should be only a couple of percentage points, else the conversion will be ineffective due to the high face count.
The output reported on the
FLUENT console is the number of created polyhedra and the resulting maximum cell skewness.
