Integration of the Coliseum Plasma Simulation Tool with the Charging Code, Nascap-2k (Preprint)

Abstract

This paper presents results from an effort to integrate the AFRL plasma modeling tool Coliseum with the SAIC/SEE, AFRL/VSB charging code Nascap-2k. Coliseum is used to compute the current collected by the test article at a fixed surface potential. Charging of the object is then computed by Nascap-2k and the new surface potential is exported to Coliseum. The process is iterated until surface potential reaches steady state. This approach is validated by modeling the floating potential of a conducting sphere as a function of electron temperature.
