Abstract:
An algebraic variational multiscale?multigrid method is proposed for large eddy simulation of turbulent flow. For this purpose, level-transfer operators from plain aggregration algebraic multigrid methods are employed for variational multiscale large eddy simulation. In contrast to earlier approaches based on geometric multigrid methods, this purely algebraic strategy for scale separation obviates any coarse discretization besides the basic one. Operators based on plain aggregation algebraic mul...     »
