@misc{10481/105509, year = {2025}, month = {4}, url = {https://hdl.handle.net/10481/105509}, abstract = {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 differs from the previous one in that 1) it implements a more systematic handling of round-off errors, 2) the set of examples has been updated, and 3) it allows including a single voxelized box as a geometry module. With the last optional feature, a Monte Carlo code can readily be used for describing irradiation processes with complex material structures, such as medical treatments.}, organization = {Ministerio de Ciencia, Innovación y Universidades (projects PID2021-123879OB-C22 and PID2022-137543NB-I00)}, organization = {ERDF - Junta de Andalucía (FQM387, P18-RT-3237)}, publisher = {Elsevier}, title = {PENGEOM -- A general-purpose geometry package for Monte Carlo simulation of radiation transport in complex material structures (New Version Announcement)}, doi = {10.1016/j.cpc.2025.109634}, author = {Almansa, Julio and Salvat-Pujol, Francesc and Díaz Londoño, Gloria Maria and Carnicer, Artur and Lallena Rojo, Antonio Miguel and Salvat, Francesc}, }
