We will start with splitting the fluid region boundaries first:
The Boundary Patches dialog will appear on the display. Surfaces belonging to the fluid region will also be color coded according to their patch definition. All other surfaces will be translucent, as shown below:
The Boundary Patches dialog can be used to select a patch or patches and create a new boundary from the original. Note that you can also select the patch directly on the model by clicking on the appropriate face - the corresponding patch number will be highlighted in the dialog. Multiple selections can be made by pressing and holding the Ctrl key while selecting each patch.
The following boundaries need to be created for the fluid region:
To define the first boundary in the table, do the following:
The completed panel is shown below:
A new boundary node will be created called Inlet, which will appear in the simulation tree:
Note that the boundary patch listing will be updated with the newly extracted boundary patch removed. The boundary will also be removed from the model display.
The completed list of boundaries for the fluid region is shown below:
The original boundary for the fluid region (Boundary 1) is now composed of surfaces that belong solely to the interface plane between the fluid and solid regions. This will make the interface definition easier later on by having all the surfaces in one boundary.
Next we will rename the original boundary and set the boundary types for each.
