Summary: | A new open source tool for fluid simulation of multi-component plasmas is
presented, based on a flexible software design that is applicable to scientific
simulations in a wide range of fields. This design enables the same code to be
configured at run-time to solve systems of partial differential equations in
1D, 2D or 3D, either for transport (steady-state) or turbulent (time-evolving)
problems, with an arbitrary number of ion and neutral species. To demonstrate
the capabilities of this tool, applications relevant to the boundary of tokamak
plasmas are presented: 1D simulations of diveror plasmas evolving equations for
all charge states of neon and deuterium; 2D transport simulations of tokamak
equilibria in single-null X-point geometry with plasma ion and neutral atom
species; and simulations of the time-dependent propagation of plasma filaments
(blobs). Hermes-3 is publicly available on Github under the GPL-3 open source
license. The repository includes documentation and a suite of unit, integrated
and convergence tests. |
