Setup of Turbo Region
 

Hi

One of my component has no hub (the hub is coincident with the rotational axis of turbomachine). If I left it blank, I could not initialize the component in turbo mode in CFD-Post, and hence I my plots like blade-to-blade and meridian will miss out the component. Is there any way to solve this problem? Thank you in advance.

Hi,

I have exactly the same problem. Have you obtained a solution yet?

Kind regards
Francois

Hello,

you can try to define a "Hub Curve" that is coincident with your rotational axis. Just create such a line.
Then: In the Turbo tab when editing the initialization of your mesh, go to the definition tab. There you can expand the option "Background Mesh". For Hub Curve: Switch from "From Turbo Region" to "From Line" and pick the line you defined.

Does that work?

It worked...
 

Hi Simon

Thanks for your reply.

I had to play around a little, but your suggestion worked perfectly. Basically, the line that needs to be defined as the 'hub curve' should be defined for the specific domain only, if you work with a multi-domain setup that was 'stitched' together by means of interface boundaries. Furthermore, the line needs to be the exact length that is required and not too long or too short.

Thanks once again.
