Benchmarking aggregation AMG for linear systems in CFD simulations of compressible internal flows
Electronic transactions on numerical analysis, Tome 37 (2010), pp. 351-366
The performance of parallel implementations of three fundamentally different aggregation AMG (algebraic multigrid) solvers, including novel k-cycle methods, for systems of linear equations appearing in industrial CFD simulations are examined. The results show that the k-cycle methods are a good choice for cases with less than 20000 unknowns per process if the cost of the setup tends to become critical; for most other applications, however, established methods proved to be equally efficient or superior.
