PENGEOM — A general-purpose geometry package for Monte Carlo simulation of radiation transport in complex material structures (New Version Announcement)

A new version of the code system PENGEOM, which provides a complete set of tools to handle different geometries in Monte Carlo simulations of radiation transport, is presented. The distribution package consists of a set of Fortran subroutines and a Java graphical user interface that allows building and debugging the geometry-definition file, and producing images of the geometry in two- and three-dimensions. A detailed description of these tools is given in the original paper [Comput. Phys. Commun. 199 (2016) 102–113] and in the code manual included in the distribution package. The present new version corrects a bug in the Fortran subroutines, and it includes various improvements of the Java graphical user interface. The previous version of this program (AEYH_v1_0) may be found at https://doi.org/10.1016/j.cpc.2015.09.019.
