How to change the size of the design grid?

[jiehuang008]

Hi Jesse,

I'm trying to change the size of the design grid (like change from 40nm to 80nm), but I can't find where can I change it. This problem has been bothering me for some days, could you help me with that?

Thank you very much!

Hi! I use the unitless system that meep also uses, so changing the grid size requires resizing all your other parameters (such as frequency). Please see https://meep.readthedocs.io/en/latest/Introduction/#units-in-meep

Hello Jesse,
I am very interested in your research. I understand that you used the Meep method to build a grid in your program. However, I'm still not clear on the specific correspondence between parameters such as electromagnetic wave wavelength, frequency, and the parameters used in the program. Could you briefly explain this to me?
Thank you very much!
