I am trying to simulate tapered rib waveguide in Lumerical MODE, using EME analysis. However, the program keeps crashing with 'EXC_CRASH(SIGABRT) exception. That happened multiple times with different actions causing it ranging from mode convergence sweep, running a simple sweep to determine change in s-parameters vs misalignment to a bizarre case when it just closed without any action taken previously.
I am using Lumerical 2020 R2.4 on MacOS Mojave (10.14.6).
Here’s the report I’m getting after crash. Thanks in advance (97.9 KB)
