Hi, dear Meep users, I am a beginner of Meep. I write a simple meep
code, and run it at the server of my department. However it can not
calculate a final result, though it is just a simple code. Could you
please tell me how to simply this code? Thank you very much.~
Initializing structure...
Working in 2D dimensions.
block, center = (-5,5,0)
size (10,1,1e+20)
axes (1,0,0), (0,1,0), (0,0,1)
dielectric constant epsilon = 11.9
block, center = (2,6.5,0)
size (10,1,1e+20)
axes (1,0,0), (0,1,0), (0,0,1)
