Decoupling and Block Preconditioning for Sedimentary Basin Simulations

  title={Decoupling and Block Preconditioning for Sedimentary Basin Simulations},
  author={Robert Scheichl},
The simulation of sedimentary basins aims at reconstructing its historical evolution in order to provide quantitative predictions about phenomena leading to hydrocarbon accumulations. The kernel of this simulation is the numerical solution of a complex system of partial differential equations of mixed parabolic-hyperbolic type. A discretisation and linearisation of this system leads to large ill-conditioned non-symmetric linear systems with three unknowns per mesh element. The preconditioning… CONTINUE READING
