Warning from Green's Function

 WARNING  3489: Too many integration intervals are required for the potentials

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.
