Hi Experts,

I have an aircraft C-130 model (attached image). The model is failing during the union process. Could anyone suggest how to resolve this issue so that it can proceed successfully?

Thank you in advance for your help!

    Hi @Sunanda ,

    The model seems to have a lot of assembly groups and some faces are creating errors while unioning. I suggest you union the parts one by one, and see which part/parts of the geometry is causing the error. You can also use the Repair Part feature or other Repare options when you get error in a union for a given geometry part.

    On the other hand, if you have access to the original CAD (outside of FEko), you can try to export it under a different file type and test importing it into Feko again.

    Best Regards,

    Zeina

    Thank you for your response. I am a new user in Feko. I am not introducing Repair Partfeature or other Repare options. Do you have any manual or tutorial for that ?

    Sure, they are available under the Transform menu, in the Repair Group:

    You can find more information about each one in the User Guide.

    May I ask few more issues in feko simulation?

    Instead of a full array. I would like to replace a farfield source setup on a plane, but there also showing some mesh error . Can I share you details hor to fix that mesh error?
