Hi, I'm getting the following error for mode area calculations. Both the field and the index monitors are set to the same settings with 200 frequency points each. Any idea how to fix this?

Please use

mode(1:sz(1),1:sz(2),1:sz(3),i)

with loop sz(4).

as E and n are 4D matrices (x,y,z,f).

eg:

for (i=1:sz(4)) { # normalize each frequency

mode(1:sz(1),1:sz(2),1:sz(3),i) =

Thanks. So in order to run mode area for 3D simulations, we should always change the code according to your last reply, right?

I believe so, since the monitors have 4 dimensions. You can pinch them for any singleton.
