I want to mesh and get error

 

Sphere1.Region58 breaks the symmetry definition. Either it does not have a symmetrical counterpart, or it is not symmetrical around the plane.

 

How can i remove those planes?

    Hi bobo44,

     

    From the image, it would appear that the model isn't symmetrical.  There are three types of symmetry (geometric; electric; and magnetic symmetry).  For each one, you need to understand how the fields and currents will behave in order to know which one is correct.  

     

    For this example, I would suggest switching off symmetry planes altogether.  You can do this in CADFEKO on the 'Solve / Run' tab -> 'Solution settings' group -> Symmetry.  You can learn more about how to utilise symmetry from the User Manual:

    • '3.11.1 Symmetry' explains how to change the symmetry settings in CADFEKO.
    • '26.1 Utilisation of symmetry' gives a more scientific overview of how symmetry can be interpreted and used in FEKO models.

    I hope this resolves the problem for you.

     

    Kind regards,

    Andries
