Hi Giovanni,

Thanks for that additional information. If you can see the field results but there is no option to calculate the farfield results, I think you are right that the issue may be that the dimension of the monitor is not correct. If you are using a 2D FDTD simulation, then the monitor type should be linear in order to calculate the farfield. What monitor type (point, linear, 2D or 3D) are you using?

However, I am surprised that the error message is about frequency being out of range; usually, if there is an issue about dimensions with farfield calculations, the error message reports that it is impossible to determine the surface normal. Can I also ask, what version of Lumerical are you using?

Best,

Anna
