Title: A semi-automated procedure for creating geometry and background plasma input files for the GTNEUT 2d neutral particle transport code using the uedge plasma edge code
Author: Friis, Zachary Ward
Abstract: The GTNEUT code1-3 can provide a computationally economical and accurate calculation of neutral particle transport in the complex 2D geometry to the tokamak divertor, scrapeoff layer and edge regions inside of the separatrix. However, the GTNEUT code requires a geometric input file describing this geometry and a background plasma file describing the plasma density and temperature in the various geometric regions. This report describes semi-automated procedures: i) for using (and extending) the input preparation capability of the UEDGE4-5 code to generate a GTNEUT geometric grid input file from a DIII-D EFIT file and ii) for using the plasma density and temperature distributions calculated with the UEDGE code to generate the background plasma input file for GTNEUT.
