That's what I set for method A (auto nonuniform, accuracy=1, standard PML=16), with mesh size=(0.1,0.1,0.02) um, which diverged at autosutoff = 0.0025. I am now using a longer time and higher auto shutoff limit of 0.05, along with a finer mesh (0.08,0.08,0.02)um, boundary setting of X min/max's standard PML layer =32, and Y/Z = Metal. Other settings are the same: auto non-uniform mesh, accuracy 1.
