Descripton
This section provides a high-level overview of the functionalities, underlying numerics, and algorithms of PARALLAX. It is not a comprehensive reference for all interfaces, but rather an introduction to using PARALLAX with example-driven explanations. The following components are covered:
- equilibrium: Describes, how the magnetic field structure is defined and gives an overview on available geometries.
- mesh: Defines the logically unstructured Cartesian R,Z mesh (poloidal plane) and its components.
- Flux-Coordinate independent approach: Describes the discrete parallel operators within the FCI approach.
- field solver: Outlines the field solver, including the key role of the multigrid preconditioner.
- polars: Describes the polar mesh and the associated operators.
- 3D solver: Explains the 3D solver, involving MPI communication across poloidal planes.
- 3D visualization support: Provides auxiliary functionality for 3D visualization using the VTK library.
