warning message in FEKO

Dear all,

 

Recently, I try to use a near field data as the source, and try to get it's far field results.

However, it shows a warning message as below:

 

WARNING 3411: No accurate power calculation possible if two non-orthogonal elementary dipoles of the same type are at the same position
Received message from server process 2:
WARNING 2407: Computation of the near field of a Hertzian dipole not possible at the dipole location

 

Could you help us check what does it exactly mean in this case?

Is there any solution to solve it?

    Hi Mel,

     

    After I upgrade Feko to version 2019, and try to solve the same problem, another similar warning show up again as below, please check:

     

    The following message from the master process (MYID= 0):
    WARNING 53119: Possibly inaccurate active power (far field gain) when using equivalent sources in a coupled environment

     

    is there any suggested solution to solve it?

    The E-fields will be correct. The gain could be wrong since the source power (upon which the gain is based) cannot be accurately determined.
    There is no way around this.

    Hi Mel,

     

    Is this warning message affect the results of the power received by near field receiving antenna?

    Near field receiving power is not affected by this warning.
