You can update the properties of any defined boundary using the Update Boundaries task. This task can be added to the workflow as many times as you require.
Note: This task involves zone assignments based on naming conventions of various boundaries. See Prerequisites for the Fluent Guided Workflows for more detailed information.
Choose a Selection Type as either by label or by zone.
(optional) Use the Filter button to filter the table contents based on a particular column.
(optional) Rename any Boundary Name by double-clicking the label in the table and entering a new name.
You can also rename a boundary by selecting it in the table, right-click, and select Set Boundary Name in the context menu, and provide a new name directly in the menu.
(optional) Re-assign any Boundary Type to another value by selecting a type in the table and using the corresponding drop-down menu. Choices include:
velocity-inlet
pressure-outlet
pressure-inlet
pressure-far-field
mass-flow-inlet
mass-flow-outlet
outflow
symmetry
wall
internal
interface
overset
outlet-vent
intake-fan
inlet-vent
exhaust-fan
fan
porous-jump
radiator
Multiple boundaries can be assigned a specific type all at once by selecting them in the table, right-click, and select Set Boundary Type in the context menu, then designate a type for the selected boundaries directly in the menu.
Note: If the Update Boundaries task is inserted into the workflow after an Extrude Volume Mesh task or a Transform Volume Mesh task, then you will need to manually ensure that any internal boundaries are not assigned on external zones (and vice versa).
(optional) By default, the table only lists external wall boundaries. Select the List All Boundaries to see additional boundaries, such as fluid-fluid internal boundaries.
Note: Toggling the List All Boundaries option will discard any changes you may have recently made in the table.
When you are satisfied with the boundary assignments, click Update Boundaries.
If you need to make adjustments to any of your settings in this task, click Revert and Edit, make your changes and click Update, or click Cancel to cancel your changes.
Multiple boundaries can be visualized all at once by selecting them in the table, right-click, and select Draw Selections in the context menu.
Use the Draw Boundaries button to visualize all boundaries or just wall boundaries.
Once all boundaries have been updated, proceed to the next step in the workflow.
Additional boundary types can be created using the Add Boundary Type task (see Adding Boundary Types).
