Abstract

CEPXS/ONELD is a discrete ordinates code capable of modeling the fully coupled electron-photon cascade at high energies. Version 2.0 of the CEPXS/ONELD code package has been designed to allow users who are not expert in discrete ordinates methods to fully exploit the code´s capabilities. The most significant enhancement is that the finite differencing schemes that are associated with the discrete ordinates method are automatically selected by the code. Adjoint or inverse transport calculations kerma predictions and transport in one-dimensional spherical and cylindrical geometries are also allowed in this latest version
