With the next major release of the
DEGAS 2 Monte Carlo neutral
transport code
,
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
approach.
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.
