Abstract:

In the present paper an implicit time accurate approach combined with multigrid and preconditioning is used for the large-eddy simulation of low Mach number flows. It will be shown that the present approach allows an efficiency gain of a factor 4 to 7 compared to the use of a purely explicit approach. The efficiency varies according to the test case grid clustering physical time step and requested residual drop.
