PenMesh is a software package that combines a state-of-the-art Monte Carlo simulation algorithm and a modern computed-aided design (CAD) geometry model with the purpose of simulating radiation transport across complex, free-form objects. PenMesh uses the particle transport physics from the PENELOPE 2006 package and a geometry model in which objects are defined by closed triangle meshes. The main program, tally and source routines are based on the penEasy 2006 package, extended with the tools from the penEasy_Imaging package to be able to generate a radiographic image as the output of the simulation. Currently, the main application of penMesh is the simulation of clinical x-ray imaging systems using detailed anatomical phantoms. However, the code is general enough to simulate any other situation involving photon, electron or positron transport, as long as the simulation stays within the applicability range of PENELOPE.
