Hello Nicolino, 

The error message indicates that the Poisson's ratio for one of the bodies in your air intake model does not fall within the acceptable range required by Discovery. To resolve this issue, you should check the material properties assigned to the body highlighted in red and ensure that the Poisson's ratio is set to a value between 0.01 and 0.5. 

Can you please check if the materials defined to that body is within this limit? If not, please update and see if that helps. 

You can also refer Structural Simulation Using Ansys Discovery | Ansys Courses & Fluid Flow Simulation Using Ansys Discovery | Ansys Courses for more information on setup and siulation using Ansys Discovery. 

Regards,
