Hi, 

I have an antenna measured and obtain the XML format of the nearfield source.

For the easy use of this fieldsource, I wanted to convert this data into the FSM format without changing the size of the box.
I was trying to create the fieldsource by importing the XML file to CST Studio Suite, run the simulation to export the nearfield but it looks like the size of the nearfield box has been changed which is not acceptable for the workflow that I am currently working with.

Is there a way to change the XML measured antenna nearfield model into FSM file format?

Thanks!
