[TurboGrid] PyTurbogrid NDF File Format

zacko · May 6, 2024, 07:32

Hello,

I am currently trying to dig into PyAnsys, especially PyTurbogrid.
Currently, the API does not support direct import of the usual .curve files.
It will be implicitly stated in an .inf file.
But, loading the curve files through an .inf file, limitations of the API are present.

Therefore, I would need to use the Multi_blade_row API, which needs an NDF file.
I looked everywhere, but nowhere is a good explanation how this file should look for Turbogrid, in order to specify my .curve files or other blade parameters.
Has anyone an example file or any hints how I could create such an .NDF file?

Thank you and kind regards
Daniel

Hello Daniel,

If you are generating your blade geometry in BladeGen or Blade Editor, you can import your blade geometry information in Design Modeler by using CAD Import => Write NDF: Blade CAD Import Files: feature.
The workflow is attached.

Best regards
Bora

Hi Bora, thanks for the information.
I don't work in Bladegen , therefore I was looking if there would be a manual way of putting my already existing coordinates into that format for pyTurbogrid. But, might be not possible.
Maybe they add a proper method for the standard curve files in the future.
