Extracting data in 3d format

So far, I have been extracting abs(emwHz) values for given parameter in a 2D cutplane in my loop antenna model. I would like to extract it in a 3D grid format.
However, most methods of trying a grid 3D dataset has resulted in errors, where Hz is an undefined variable, like as shown below.
"Undefined variable. - Variable: comp1.emw.Hz - Global scope Failed to evaluate expression. - Expression: comp1.emw.Hz"
Is there a way to overcome this error, or if not, to obtain Hz values in a 3d format?

I have attached the file. I have only left the solution, datasets needed and the derived values i tried to use. Unfortunately, I dont have access to the latest version of COMSOL so this is the best i could work with.
