Sophia and Steve, Thanks for the info and suggestions…the most straight-forward work-around might be just to do an auxiliary simulation with a “zoomed” computational space in the critical region at appropriate resolution, then overlay the results into the bigger picture. A seamless overlay would require careful attention to the geometrical object specifications.….have to think some more about the best approach.
Lumerical provides this two-resolution feature but Lumerical is proprietary, commercial and not cheap. Best regards, John > On 11 Sep 2017, at 03:04, Steven G.
