Thanks in advance for any insightful replies!&nbsp;&lt;\/p&gt;&lt;p&gt;I am running a simulation in a cuboid. The XYZ origin is at the centroid of the cuboid. I have two FD monitors, one in the XY plane (plan view) and one one in the YZ (end) plane, both passing through the origin (as highlighted in the red boxes on the green cuboid in the bottom left panel of screenshot 2 below). Looking at the point where the two orthogonal planes intersect (highlighted by red boxes on the screenshots), I am confused as to why at the point where the two slices intersect, the XY results clearly show the E field vectors&nbsp;<em>diverging<\/em> through the boundaries, but the YZ shows the field vectors at the same point <em>converging<\/em>.
