Unable to edit FDTD geometry
I am using the example from https://support.lumerical.com/hc/en-us/articles/360042096033-Plasmonic-metamaterial-absorber
I can get the expected results shown on the website.
However, why can't I edit the size of FDTD in its geometry tap?
I would like to scale up the whole model in the example, but I cannot change the FDTD.
Could someone please shed light on it?
