Ultra-Fast Reactive Transport Simulations When Chemical Reactions Meet Machine Learning: Chemical Equilibrium

  title={Ultra-Fast Reactive Transport Simulations When Chemical Reactions Meet Machine Learning: Chemical Equilibrium},
  author={Allan M. M. Leal and Dmitrii A. Kulik and Martin O. Saar},
  journal={arXiv: Optimization and Control},
During reactive transport modeling, the computational cost associated with chemical reaction calculations is often 10-100 times higher than that of transport calculations. Most of these costs results from chemical equilibrium calculations that are performed at least once in every mesh cell and at every time step of the simulation. Calculating chemical equilibrium is an iterative process, where each iteration is in general so computationally expensive that even if every calculation converged in…

POET (v0.1): speedup of many-core parallel reactive transport simulations with fast DHT lookups
POET (POtsdam rEactive Transport), a research parallel reactive transport simulator integrating algorithmic improvements which decisively speed up coupled simulations, is developed and an original implementation of the distributed hash table (DHT) mechanism is implemented to cache the results of geochemical simulations for further reuse in subsequent time steps during the coupled simulation.
