Calcul scientifique

toofus

Toofus rassemble une collection d'outils sous la forme de fichiers d'en-tête autonomes qui peuvent être inclus dans les sources C++ sans autre complication.

rockable

Rockable est un code DEM écrit en C++. Les deux principales spécificités du code sont (i) l'utilisation de formes sphéro-polyédriques, (ii) la gestion d'interfaces cassables.

p-tracker

p-tracker est un outil pour les corrélations d'images numériques (DIC) écrit en C++. Le projet a été initié sous le nom de tracker (sans le p- avant). La particularité du code est qu'il peut suivre les positions 2D des particules sur les photographies sans en perdre. Cela n'est pas possible avec un outil de corrélation conventionnel, aussi performant soit-il. L'accent mis sur la nature discrète du suivi explique pourquoi la méthode est appelée Particle Image Tracking (PIT) plutôt que DIC. Cependant, l'outil est toujours capable d'effectuer le DIC.

mpmxdem

mpmxdem est une solution polyvalente permettant d'exécuter des simulations par la méthode des points matériels (MPM) avec des modèles constitutifs classiques. En outre, il offre la possibilité d'intégrer des simulations par la méthode des éléments discrets (DEM) 2D/3D avec des conditions aux limites périodiques au sein d'une simulation MPM. Cette intégration permet de générer en direct une loi constitutive homogénéisée numériquement.

Description: Gravity hazards are a major concern to those living in mountainous areas. To protect infrastructure and human life in these areas, engineers require numerical tools for trajectory analysis, for application from fragmental rockfalls to large-scale avalanches or landslides. This book explores state-of-the-art methods to model the propagation (flows and stops) of masses, using the discrete element method (DEM) to study the evolution of kinetics during an event. Taking into account the shape of the blocks and the topology of the terrain provides an explicit and sophisticated consideration of geometries, eliminating the need for stochastic inputs to rockfall simulations. This method is validated experimentally, before the authors apply it to real case studies. The book ends with an introduction to and comparison with the material point method (MPM), a new and promising approach able to bridge the gap between cases dominated by discreteness and those involving a very large number of elements. Engineering consulting firms, researchers and students should find the approaches outlined in this book useful, whether designing prevention and protection systems for gravity hazards, or exploring new ways to model gravity hazards.
