Charge-conserving local field solvers are widely used in today's electromagnetic plasma simulations. As in such codes the charge does not appear explicitly, the injection of new particles into the computational volume and their removal upon reaching the boundaries requires some cautiousnes. While for quasineutral plasmas a particle injection in accordance with charge conservation can be realized quite easily, the injection of noneutral plasmas with spatially separated electron and ion sources might lead to the emergenceof unwanted divergences in the electric field. With a three-dimensional charge-conserving electromagnetic plasma simulation, we evaluate several injection schemes of nonneutral plasmas and present a method the rigorously respects conservation of charge and thus allows injection of nonneutral plasmas without producing unwanted divergences in the electric field.
