Hi Bagus,

That is a really good question. Full Multigrid (FMG) initialization is used to obtain better initial solutions to complex flow problems. These initial solutions help accelerate the flow convergence. Furthermore, you can check this resource for your reference ANSYS FLUENT 12.0 Theory Guide - 18.7.1 Overview of FMG Initialization (enea.it)
