Hello,

solving for the FDE modes in my waveguide gives fields in Ex, Ey, Ez, Hx, Hy and Hz. The Ey field is shown in the built-in viewer as:

when I use the command :

Ey_mode1 = pinch(getdata("mode1","Ey"))

I get an array with all elements assigned with a value of 0. The same thing happens for Hy. 

This does not happen with Ex_mode1,Hx_mode1,Ez_mode1 and Hz_mode1. Both Ey and Hy have fields which are shown in the built in viewer, yet when this data is exported to array , all the elements of the array gets stored as 0.

Can someone please explain why this is happening and how I can get the data associated with the Ey and Hy modes?Thanks

Your script is correct. Make sure you visualize the same Ey.

You can also use

E=getresult("mode1","E");

to get the vectorial fields, and then extract Ey from the dataset;

Ey=E.Ey

thanks for clarifying.
