Abstract:

TOUGHREACT is a simulator for nonisothermal multiphase reactive geochemical transport in saturated geologic media. In recent years, there has been an increasingly need in application of fieldscale simulation, which leads to intensive computational efforts. In order to scale up the simulation model and improve the performance of the simulator, the authors analyzed the mathematical model of coupled simulation and executed time proportion; designed a parallel computing scheme of numerical simulation on coupled reaction; reorganized the structure of coupled simulation program. Experiments on distribute memory computing nodes show 2—3 times speedup in simulation time.

Key words: coupled geochemical reaction; , parallel computing, numerical simulation
