Half Planar Green's Function

  I have a fairly large metallic structure over a half planar green's function. I have received the following warning

 

 WARNING  3595: Too many interpolation points for the substrate
    See also message in the output file PEC_1.out

 

What does this indicate? How unreliable is the solution due to this warning?

    Hi Pmcardle

     

    The structure is quite likely electrically too thick.

     

    Sometimes the warning message is conservative. To check it, calculate the near field inside the layer and run it over a frequency range. 

    The warning should disappear at higher frequencies. If the trend in the near field curve is consistent down to the frequency you require (maybe a straight line and does not pick up noise at low frequencies) then the results are quite likely reliable.
