Hello everyone,

I'm now working on the simulation of wind turbine using turbomachinery module. but when I ran the case, there is an erro:
Check_geometry: some faces of the initial mesh belong to different rotor/stator sections. These sections must be initially disjoint to rotate freely.

I think there is something wrong with the rotor definition. Do you know how to choose the selection criteria in the rotor definition and face joining? Thank you very much.

Hello,

The faces must be disjoint (i.e. not already connected) in the initial mesh.

Thanks for your reply ,Yvan.

I made two different mesh, rotor and stator. The joining face are"interface 1" and "interface2". In the first import mesh step. I choose all[] at the joining face(optional) as the image. after that in the turbomachinery module, I choose interface1 or interface 2 in the joining face . Is that right? Many thanks. I get a new erro. "cannot achieve to reorient the joining face" What dose that mean?
Thank you !

Hello,

If do you join rotor/stator interface faces in the preprocessing stage, they cannot be "disjoint" at the beginnig of the rotation steps.

Hi Yvan，

Many thanks for your suggestion. Now it works!
