INGRID Introduction

INGRID is an interactive grid generator for tokamak edge-plasma modeling capable of handling magnetic-configurations with two x-points in the computational domain.

INGRID analyzes EFIT data in order to classify the magnetic-topology, and generate the appropriate gridue formatted file for use in simulation code UEDGE.

Key features of INGRID include:

1. Support for single-null, unbalanced double-null, and snowflake (15, 45, 75, 105, 135, 165) configurations

2. Python based code with GUI and scripting usability

3. UEDGE friendly

4. Portable YAML parameter file driver

5. 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).
