An overview is presented of recent advances in the filtered density function (FDF) modeling and simulation of turbulent
combustion. The review is focused on the developments that have facilitated the FDF to be broadly applied in large
eddy simulation (LES) of practical flows. These are primarily the development of a new Lagrangian Monte Carlo
solver for the FDF, and the implementation of this solver on Eulerian domains portrayed by unstructured grids. With
these developments, it is now much easier to apply FDF for predictions of reacting flows in complex geometrical
configurations
