New Geometric Capabilities of DRAGON

Abstract

In this paper we describe the new 2-D and 3-D supercell geometries that can now be treated by the EXCELL module of the code DRAGON. We also present the new pre-homogenization module that. can be used to reduce the dimension of the collision probability matrix. Finally we discuss the modifications to the code that were required to extend the use of periodic boundaries to a more general class of geometries.
