Export results from ANSYS into other files!

[AndrewSpotlight]

Hi,

I am modeling a 2D Magnet in ANSYS and I want to export the results of the magnetic flux intensity around the magnet to some .txt or .xl file, so that I can use them in Matlab for further analysis. I tried to export the ANSYS results into some array but keep getting warning "Requested data is not stored for node" and "*GET command is ignored". Has anybody encountered the same problem before? Or any suggestion on how to export specific results from ANSYS?

I put my ANSYS command below. Hopefully someone can help! Thanks!
