Full field modeling of microstructure evolutions at polycrystalline scale is nowadays a very active field of research. Within this context we have been working in tight collaboration with industrial partners in order to be able to predict microstructural evolutions of metallic material due to recrystallization and grain growth phenomena. This collaboration had lead us to the development of a numerical framework based on the Level-Set method that allows to account fro complex microstructural evolution. These complex phenomena includes grain growth, Smith-Zener pinning and, in particular, static, dynamic and post-dynamic recrystallization. In this way the motion of the grain boundaries of microstructures is simulated accurately.

The general numerical framework will be presented along with recent developments that allowed us to significantly improve the performance of our approach. Our on-going developments aim at the enhancement of the existing capabilities of our numerical tools in order to account for high grain boundary energy and mobility. Different examples will the used to illustrate the robustness of the numerical approach as well as its capabilities to accurately simulate microstructural evolutions. Finally, some current challenges for the forthcoming years will be discussed.
