ILU as a solver in a parallel multi-grid flow prediction code
In this paper ILU methods are considered as solvers in a parallel multigrid flow prediction code. A parallelization strategy for the inherently recursive ILU methods is discussed with respect to their numerical and parallel efficiency. By a number of numerical experiments the computational performance of the ILU approach is investigated. The studies include comparisons with preconditioned conjugate gradient methods as well as investigations concerning the influence of flow properties and algorithm parameters on the convergence behaviour of the methods.
