25.15.2 Steps in Using FMG Initialization

You can access the FMG initialization procedure using the text user interface (TUI) once the standard flow initialization is performed (see Section  25.6.4) or if valid flow data is available (i.e., through reading a data file).

To customize the FMG initialization, type the following command :

solve $\rightarrow$ initialize $\rightarrow$ set-fmg-initialization

You will be asked to enter:

To perform the FMG initialization, type the following command :

solve $\rightarrow$ initialize $\rightarrow$ fmg-initialization

When you are prompted to Enable FMG initialization? [no], type yes.

When verbose mode is selected and the FMG initialization is being executed, FLUENT will first output the multigrid level information followed by convergence history for the FAS multigrid cycle on each level. The normalized residual value is printed after ten FAS cycles or when the number of FAS cycles is reached. The output will indicate when convergence is reached on each level and when the solution is being interpolated to the next level.
