Simulations of three dimensional orbital debris impact problems, using a parallel hybrid particle-finite element code, show good agreement with experiment and good speedup in parallel computation. The simulations included single and multi-plate shields as well as aluminum and composite shielding mat

โฆ Synopsis
In this paper the advantages and disadvantages of using a hybrid particle code approach to simulate highly nonlinear plasma phenomena on scale lenghts beyond the Debye length are discussed. The formalism for building hybrid codes is discussed. It is shown that many features not attainable with traditional MHD formalisms can be simulated on scale sizes that can approach planetary scales. Results of 2~and 3-D simulations will be discussed to demonstrate the strengths and weakness of this approach.

A new simulation code using the hybrid approximation for modeling extraterrestrial plasma processes is described, which can be used in an arbitrary threedimensional, ordered, hexahedral grid. Maxwell's equations are transformed using common tensor analysis and solved by a finite differencing scheme.
The adaptation of PIC methods requires the ability to change the number of particles during the calculation. For PIC methods it is not sufficient to adapt the computational grid. It also necessary to control the local number of particles per cell (particle rezoning) by increasing or decreasing its v
