Renaming the Region

The boundaries read in from file hex.ccm already have suitable names but we shall rename the region.

Open the Regions node, right-click on the Default_Fluid node and then select Rename...

The Rename dialog will appear.

Change the name to Fluid.

Click OK.

Open the Fluid > Boundaries node.

Select each boundary node in turn. The corresponding boundary location will be shown in the geometry scene.
