I am trying to solve for the scattered electric field from a gold nanoparticle on a semiconducting substrate, using a 2-step process identical to the example file "Scatterer on Substrate." When solving for my model I get an error saying the field cannot be solved for in one of the PML domains, I have tried to determine why this error is occurring and compared my model to the example file but the setup seems to be identical between the two (except for the geometry of course).

Has anyone experienced this problem before and have an ideas of what the error might be? I am quite puzzled by this because it works in the example file, but not the one I have built.

Thank you,

Curtis

After some more investigating I have found the solution to my problem. For anybody who is having the same problem, the solution to my problem was that I did not define the field as zero in the PML regions.

Hi Curtis,

I am also following the same tutorial " scatter on substrate" and trying to solve the absorption cross section of metal nanoparticles. Like you said, the settings are identical except for the particle size which I changed to small one. I get strange results. I am pretty sure this is coming from the meshing size related to the particle size. But I am not sure how to choose proper meshing size in my case. I don't know whether it is same problem or not Besides the field in PML regions.

Thanks.
Kuai
