摘要: The formulation of strategies for high-order discretization methods compressible flow simulations is now to a certain extent understood, whereas the development techniques eciently solving resulting discrete equations has generally been lagging behind. Needs and constraints change greatly from case case. In order achieve bestpractice combination all ingredients composing global strategy, target-specific tuning required. We here take into consideration Spectral Dierence Euler equations. investigate convergence acceleration given by full multigrid strategy implemented in conjunction with hybrid multilevel relaxation technique. also present idea time-implicit technique, representing an intermediate solution between matrix-explicit matrix-free techniques.
