Abstract :
In this paper we describe some spurious oscillatory processes at re-entrant electron stream in non-generating and generating states of a CFD. The results have been obtained with the TULIPgm code intended for full-format transient and spectral PIC simulations of CFDs. A spatio-temporal interpolation of fields has been carried out with the PWS method.
