A Grid-Free Approach for Plasma Simulations (Grid-Free Plasma Simulation Techniques)
Abstract
This project draws together a team of researchers to develop new grid-free tools for plasma simulations. The objectives are: (1) to develop a grid-free field solver, fluid model, and kinetic model, (2) to evaluate these tools in comparison with traditional mesh-based methods, and (3) to demonstrate the capability of the grid-free approach in an application of USAF interest. The field solver will use boundary integral methods and a recently developed tree code algorithm to compute the electrostatic force induced by a set of charged particles. The kinetic model will use tree-based statistical procedures for inter-particle collisions. Various hybrid grid-free simulations will be possible using these tools. The resulting grid-free approach will have several advantages over traditional mesh-based methods: it will eliminate the need for elaborate volume-meshing routines required to handle complex geometry, and will avoid the spurious numerical artifacts in the particle distribution that can arise in mesh-based schemes.
