INGRID is an interactive grid generator for tokamak edge-plasma modeling capable of handling magnetic-configurations with two x-points in the computational domain.
Key features of INGRID include:
Support for single-null, unbalanced double-null, and snowflake (15, 45, 75, 105, 135, 165) configurations
Python based code with GUI and scripting usability
Portable YAML parameter file driver
Modular design pattern for continued development efforts
INGRID was developed at LLNL PLS-FESP by Bryan Garcia (UCSC), Maxim Umansky (LLNL), and Jerome Guterl (GA).
