Numerical Simulation of Blast Wave Propagation in a Large Urban Environment: The 2020 Beirut Explosion
摘要
We present a high performance computing simulation of the 2020 Beirut explosion. Specific tools have been developed to model the blast interaction with the buildings of the whole city. A specific meshing strategy is presented to achieve an acceptable accuracy while keeping the computational cost under control. The data-driven modeling of the explosive charge is introduced, and some other numerical aspects are discussed. The predicted numerical results are then extensively compared with different kinds of observations.
