| This work investigates the implementation of the accurate Bohm condition in a Hall Thruster hybrid code. First, an extended review of the current PIC weighting algorithms at boundaries is presented. Second, the accurate Bohm condition for non-monoenergetic, variable-charge populations is implemented. Third, a generalized PIC Mach-Bohm number is defined, based on the PIC weighting formulation of the kinetic Bohm condition. Fourth, the fulfilment of the accurate Bohm condition is analysed, showing that the best weighting scheme at boundaries lead to strong numerical oscillations. And finally, several advances in boundary weighting algorithms are presented aimed at reducing the oscillations of plasma magnitudes. | |
