The Fluent VBM can be enabled through the Virtual Blade Model dialog box which can be accessed from the Models group box of the Physics ribbon, or from the tree by expanding Setup and then Models, or through the Models Task Page.
It also can be enabled using the following text user interface (TUI) command in the Fluent Console:
define/models/virtual-blade-model/enable?
Note: The VBM is only available in 3D and Parallel mode. The Serial option is deprecated.
The VBM can only be enabled when a valid Ansys Fluent case or mesh file has been set or read.
VBM's current compatibility is limited as it does not work with multiphase or inviscid flow. If any of these are active, Fluent will prevent VBM from being enabled and will display a warning message in the Console or a pop-up message.
