Surface viewer

I wish to view the fields on one of the surfaces in my LF-Magneto Quasi-Static model but cannot see how to specify the surface which I am interested in. Please can you advise?

You could perhaps try to interpolate the fields onto the surfaces of interest. To do that, you need to drag & drop the surface (from the Multi-Tree) into the Explorer tree, while in the Analysis tab. This will create a surface object for analysis purposes, with settings such at mesh discretization (minimum edge length).
To perform the interpolation itself, select both (using the CTRL key) the E field (say) and the Surface, then click Interpolate Field in the ribbon.

Thank you, I think that has solved my problem
