The Georgia Tech Neutral Transport (GTNEUT) code is being implemented to
provide a tool for routine analysis of the effects of neutral atoms on edge phenomena in
DIII-D. GTNEUT can use an arbitrarily complex two-dimensional grid to represent the
plasma edge geometry. The grid generation capability built into the UEDGE code,
which utilizes equilibrium fitting data taken from experiment, is being adapted to produce
geometric grids for the complex 2D geometries in the DIII-D plasma edge. The process
for using experimental measurements supplemented by plasma edge calculations to
provide the required background plasma parameters for the GTNEUT calculation will be
systematized once the geometric grid generation is complete.
