If you observe reverse flow or large recirculation regions near an outlet, you can
extrude the outlet face to allow the flow reversal to be contained before reaching the
outlet boundary.
Click the Geometry tab on the main
ribbon.
In the modeling window, double-click the outlet you would like to
extrude.
Note: You can also use the
Extrude tool on the Geometry ribbon for more complex extrude options. Refer
to Extrude
for instructions.
Use the white arrows to adjust.
Right-click and mouse through the check mark to exit, or double-right-click.
