Thus, providing a simulation tool able to model the whole chain becomes critical. Physical phenomena occurring during the processes are nowadays better understood, providing always more relevant models for numerical simulation. However, important numerical challenges still exist in order to be able to run those simulations with the required accuracy. This article shows how FORGE® tackles those issues in order to provide highly accurate microstructure and surface treatments simulation features applied on real industrial processes. 1 Introduction It is quite obvious that final properties of forged parts depend strongly on the main forming processes, but they also depend significantly on all the other processes of the manufacturing chain. As a consequence, the core of a metal forming Finite Element (FE) software is and remains the thermo mechanical computation of the forming processes, with a lot of efforts and innovations delivered to enhance robustness, accuracy and efficiency in this domain
