Many turbomachinery models and/or features require some information about the turbomachine that is being modeled such as the number of modeled blade rows, the number of modeled blade passages per row (or sectors), and the number of blades per full wheel. This information is used in the setup of computational methods or postprocessing functionalities. There are two method to described a turbomachine:
Using the Turbo Workflow (as described in Using the Turbomachinery Guided Workflow) automatically defines the turbomachine description.
If the Turbo Workflow is not used, you will need to enter this information manually using the following console commands:
/define/turbo-models/create-turbomachine-description
Describes the conceptual/abstract machine and CFD model setup and is required as a preliminary step to the following features:
Harmonic export (as described in Visualizing and Exporting Blade Flutter Harmonics with TWM)
Harmonic postprocessing (as described in General Fourier Coefficient Postprocessing for Turbomachinery Cases)
When this command is activated, Fluent prompts for the number of rows that comprise the turbomachine model, and for each row, you need to specify a name (or default is used), the cell IDs that define each row, the number of sectors in the 360-degree wheel, and the number of modeled sectors in the CFD mesh model.
/define/turbo-models/list-turbomachine-description
Writes the current state of the turbomachine description to the console as a result of
using the Turbo Workflow or manually entering it using the
create-turbomachine-description command.
/define/turbo-models/delete-turbomachine-description
This command deletes a previously defined turbomachine description.
