 WARNING  3489: Too many integration intervals are required for the potentials
    See also message in the output file

 

I am getting this error when using the half planar green's function. I have switched to a multilayered green's function to reduce the thickness of the material which has a small effective wavelength. Does reducing the volume help alleviate this warning? or does it only depend on the effective wavelength and size of the problem. I am still receiving this warning when I use the multilayered green's function.

    The depth in wavelengths is what determines how many integration intervals are necessary. You could try using 2 layers of half the depth each, with permittivities very similar. Say the layer had permittivity of 2, then make 2 layers, one of 2 and one of 2.001.

    What would having two layers accomplish? Would it split up the integrations in both layers?

    It should, but if the layers are really electrically very thick then the computation time would still be a prohibitive, even with split layers.
