[2C04] An implement of the ensemble simulation for urban wind condition using locally mesh-refined lattice Boltzmann method

*Yuta Hasegawa1, Naoyuki Onodera1, Yasuhiro Idomura1 (1. JAEA)

Keywords:lattice Boltzmann method, local mesh refinement, urban wind condition, ensemble simulation

局所細分化格子ボルツマン法に基づく風況解析コード『CityLBM』において,アンサンブル計算をMPI化することで大アンサンブル数の計算を行い,汚染物質拡散解析の不確実性を系統的に検証した.
