I see the following warning:

Warning 34083: UTD far field calculation when exciting with a plane wave is inaccurate (caustic problem of the UTD).


What does it mean and what should I do to fix it?

    The warning is given when a plane wave is used together with the UTD solver. The caustics for the UTD causes the far field to be inaccurate. The plane wave is, however, allowed with the UTD when calculating near fields or the received power into an ideal receiving antenna.

    Where it is required to use a plane wave and calculate the far field for an electrically huge problem, the RL-GO solver could be used.
