| Numerical Efficiency of Explicit and Implicit Methods with Multigrid for Large Eddy Simulation (2006) | |||||||||
Abstract | |||||||||
| In this paper the accuracy and efficiency of a finite-volume multigrid solver for Large Eddy Simulation (LES) is investigated. The spatial discretization method employed is a second-order accurate central differencing scheme. For time discretization of the momentum equations the implicit second-order Crank-Nicolson method and the explicit second-order Adams-Bashforth method are considered. The influences of the two time discretizations, choice of grid size and time-step size and multigrid performance on the numerical accuracy and computational efficiency are discussed..
