Computational Methods in Transport: Verification and Validation [PDF ebook] 

In a wide variety of applications, accurate simulation of particle transport is necessary whether those particles be photons, neutrinos, or charged par- cles. For inertial con?nement fusion, where one is dealing with either direct drive through photon or ion beams or indirect drive via thermal photons in a hohlraum, the accurate transport of energy around and into tiny capsules requires high-order transport solutions for photons and electrons. In ast- physics, the life cycle of the stars, their formation, evolution, and death all require transport of photons and neutrinos. In planetary atmospheres, cloud variability and radiative transfer play a key role in understanding climate. These few examples are just a small subset of the applications where an – curate and fast determination of particle transport is required. Computational Methods in Transport Workshop (CMTW) is devoted to providing a forum for interdisciplinary discussions among transport experts from a wide range of science, engineering, and mathematical disciplines. The goal is to advance the ?eld of computational transport by exposing the me- ods used in a particular ?eld to a wider audience, thereby opening channels of communicationbetweenpractitionersinthe ?eld.Theoriginalconceptforthe workshop was born at the SCa Le S (scienti?c case for large scale simulation) meeting held in Washington, DC in June 2003. The discussions at SCa Le S were lively and informative, and it was clear that the opportunity to meet with experts outside of a particular sub?eld created new insights into the problems being discussed.
