The Fluent VBM can be enabled through the through VBM Rotor Inputs dialog box or text user interface (TUI). Use the following TUI command in the Fluent Console to enable the VBM:
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.
