Description:

Application definition for storing results of the SCORE cellular automaton. ...

Application definition for storing results of the SCORE cellular automaton.

The SCORE cellular automaton model for primary recrystallization is an example of typical materials engineering applications used within the field of so-called Integral Computational Materials Engineering (ICME) whereby one can simulate the evolution of microstructures.

Specifically the SCORE model can be used to simulate the growth of static recrystallization nuclei. The model is described in the literature:
