► PROJECT | Batch mode/ Optimization

This feature can be used to prepare batch mode runs of CFturbo for systematic parameter variations (DoE) or configure optimization jobs, see Batch mode.

Load, Save

The working directory is displayed on top of the dialog.

Complete configurations as batch mode files in XML format (*.cft-batch) can be loaded by Load ... and saved by Save or Save as... .

The input CFturbo file is the currently opened project always, whose directory is specified in relative notation by default. A copy of the current CFturbo project is stored in the destination directory of the batch mode file (*.cft-batch).

If CFturbo is running inside Ansys Workbench, the batch mode configuration is saved automatically.

More information about CFturbo inside Ansys workbench is available on the CFturbo website:

Input parameters

All available parameters of the project, which can be modified manually or by an optimization software directly during a batch run, are displayed in a tree structure according to the components and design steps.

Save modified CFturbo project [not available inside Ansys Workbench]

If parameters of the CFturbo project will be modified during the batch run, the resulting CFturbo file (*.cft) can be saved optionally.

Each parameter can be activated or deactivated individually.

For activated parameters the range can be specified optionally either by

a small dialog (click on the button on right side of the range cell)


using the following syntax:




<Min. value>:<Max. value>


<Min. value>:<Max. value>:<Count>



If a discrete range definition was specified a list of the discrete values is displayed as hint when moving the mouse over the cell.

Output parameters

All parameters, which are a result of any geometry modifications during a batch run, are displayed in a tree structure according to the components and design steps.
The modified values are saved in the .cft-res file at the end of the batch run for further processing, e.g. for checking the smallest cross section between neighboring blades or the automatically calculated blade angles. These values are typically used as constraints during optimization runs.

Export actions

On this page the export actions for the batch run can be specified. Multiple export actions can be defined by selecting the export formats and the corresponding components on the right side (very similar to the Export dialog) and pressing the Add button.

Possible warnings


Possible solution

Export requirements are not fulfilled.

Some of selected components no longer fulfill the export requirements.

Remove or replace the affected export actions.

Component selection already used.

Applicable only in Ansys Workbench mode.

At least one selected component was already used for the same export interface in previous export actions. The critical export item is highlighted in red.

Remove affected export actions.
