Hello, I'm trying to use the thruster shell instruments in order to get the angular distribution of the current density produced by an Electric Thruster. However, the current density values along the centerline are at least an order of magnitude smaller than the experimental results and doesn't decrease much with the angle while the integrated current is comparable with the expected beam current.

Is the measured current density obtained by interpolation from the nodes of the numerical grid?

What mesh size do you usually use in order to get meaningful results in the area where you want to perform this measurement? Thanks,
