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.
