INGRID

Tokamak edge plasma grid generator for magnetic-topologies with up to two x-points anywhere in the domain.

Description

INGRID (Interactive Grid) is a Python based tokamak edge plasma grid generator capable of automatic generation of grids for magnetic-topologies with up to two x-points anywhere in the domain. The code generates block-structured grids in three steps:

- Analysis of MHD reconscruction code such as EFIT to identify the embedded topology.
- Generation of the appropriate Patch map which appropriately models the domain (blocks).
- Generation of the grid ready for export.

INGRID can be utilized in a GUI mode and noninteractively via Python scripts. Both modes of operation support the use of the YAML formatted parameter file.
