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:

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

• Python based code with GUI and scripting usability

• UEDGE friendly

• 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).
