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.2 p.application/pdfengcc-by-nc-nd (c) Almansa, Julio, et al., 2021https://creativecommons.org/licenses/by-nc-nd/4.0/Mètode de MontecarloTransport d'electronsFORTRAN (Llenguatge de programació)Monte Carlo methodElectron transportFORTRAN (Computer program language)info:eu-repo/semantics/article7141772021-10-08info:eu-repo/semantics/openAccess
