Dear ParaView community,
I recently simulate the EM scattering of a metallic sphere in a medium. I would like to visualize the EM field on the surface of the sphere which is inside the medium. Do you know which kind of tool should I use?
My dearest regards
Giulian

Hi !
In short, you can use `Streamlines` filter and `Glyphs` representation. Also volume rendering and `Contour` maybe of use here.
I think you may want to look at this nice webinar [Basic ElectroMagnetics Post-processing with ParaView on Vimeo](https://vimeo.com/860864669) about this exact topic
