We present results on the accuracy of a variety of two and three dimensional particle mesh methods for computing fields generated by sheets of charged particles of varying thicknesses. We show precisely how the accuracy depends on the orientation of the curve or surface with respect to the mesh. We also show why even when the charge distributed to the mesh differs significantly from the distribution that would provide the correct potential function, the computed field values on the sheet can sometimes be surprisingly accurate.

There will be a reception with light refreshments from 3:45-4:15 in the lobby of the Mathematical Sciences Building.
