The full-field modeling of microstructures evolutions has been the focus of numerous studies in recent decades. The DIGIMU® software aims to make those predictions easy to use and accessible for engineers in an industrial context. It is based on a Finite Element approach combined with Level-Set (LS) grains description [1]. 2D and 3D simulations of grain growth, Smith-Zener pinning mechanism [2], dynamic and post-dynamic recrystallization [3] are available in the current commercial version.

New important features will be added in the next version, whose release is planned for the end of 2022.
Second phase particles evolutions will be taken into account using the LS method coupled with mean-field dissolution/precipitation models. More accurate predictions of grain growth and Zener -pinning effect for heat treatments around the solvus temperature can be obtained [4]. Ostwald ripening mechanism can also be considered.
Grain orientation and its effect on the heterogeneity of the grain boundary energy will be considered using an adapted Read-Shockley formulation [5], which opens the door of advanced full-field substructure evolution analysis, continuous recrystallization, and the representation of twins boundaries.

The numerical framework behind those new features will be detailled, and illustrated on several simulations. Results show a good agreement with experimental observations.
