A Uniform Hybrid Monte Carlo Method for Simulation of Rarefied Material Dynamics

This proposal is for development and commercialization of the interpolated fluid/Monte Carlo (IFMC) method for rarefied gas dynamics (RGD). The prevalent computational method for RGD is the Direct Simulation Monte Carlo (DSMC) method, which becomes computationally intractable in the near-continuum regime. The IFMC method accelerates DSMC in the near-continuum regime, removing this limitation. Technical feasibility of IFMC was demonstrated in Phase I through a set of test computations, and many improvements of the method were made. The work in Phase II will be application of IFMC to aerospace and materials processing problems, and extension of the IFMC software as needed for the applications.
