5. 내 용 :


The charge conservation laws in general are not strictly obeyed in numerical simulations of electromagnetics and MHD(MagnetoHydroDynamics). This is due to the presence of various numerical errors. These errors can grow with time, and thereby lead to nonphysical field and flow configurations. In this talk, we present a field theoretically motivated method for the correction of these charge non-conserving numerical errors.
