ABSTRACT

With the next major release of the DEGAS 2 Monte Carlo neutral transport codegif, the user will have access to a flexible scoring capability; a standard set of neutral and background plasma scores will be included by default. A separate set of scoring arrays will be used for time-dependent coupling to fluid plasma codes. Implicit techniques are being investigated as a way to increase the time-step relative to the explicit approachgif. Satisfactory execution times will be achieved by running the coupled system on massively parallel computers. Handling of high neutral density regions will be improved via a hybrid fluid-Monte Carlo model of the neutral transport. The DG grid generation and surface data input facility is being adapted for use with DEGAS 2 to provide an easy way for the user to transform equilibrium data and CAD hardware files into DEGAS 2 geometry input.
