Domain decomposition with discrete element simulations using shared-memory parallel computing for railways applications
Résumé
Numerical simulation with discrete elements leads to several issues for large scale problems and long loading times, as for the granular dynamic simulations of the ballasted railway behavior. To reduce computational costs, we study the use of two strategies: domain decomposition methods and shared-memory parallelization with OpenMP. An example of a maintenance process, the tamping, on a portion of railway track with 7 sleepers, is simulated.
