Query: A new front-tracking Lagrangian model for the modeling of dynamic and
  post-dynamic recrystallization   A new method for the simulation of evolving multi-domains problems has been
introduced in previous works (RealIMotion), Florez et al. (2020) and further
developed in parallel in the context of isotropic Grain Growth (GG) with no
consideration for the effects of the Stored Energy (SE) due to dislocations.
The methodology consists in a new front-tracking approach where one of the
originality is that not only interfaces between grains are discretized but
their bulks are also meshed and topological changes of the domains are driven
by selective local remeshing operations performed on the Finite Element (FE)
mesh. In this article, further developments and studies of the model will be
presented, mainly on the development of a model taking into account grain
boundary migration by (GBM) SE. Further developments for the nucleation of new
grains will be presented, allowing to model Dynamic Recrystallization (DRX) and
Post-Dynamic Recrystallization (PDRX) phenomena. The accuracy and the
performance of the numerical algorithms have been proven to be very promising
in Florez et al. (2020). Here the results for multiple test cases will be given
in order to validate the accuracy of the model taking into account GG and SE.
The computational performance will be evaluated for the DRX and PDRX mechanisms
and compared to a classical Finite Element (FE) framework using a Level-Set
(LS) formulation.
