Abstract: | The development of some computational algorithms based on cellular automaton was described to simulate the structures formed
during the solidification of steel products. The algorithms described take results from the steel thermal behavior and heat
removal previously calculated using a simulator developed by present authors in a previous work. Stored time is used for displaying
the steel transition from liquid to mushy and solid. And it is also used to command computational subroutines that reproduce
nucleation and grain growth. These routines are logically programmed using the programming language C++ and are based on a
simultaneous solution of numerical methods (stochastic and deterministic) to create a graphical representation of different
grain structures formed. The grain structure obtained is displayed on the computer screen using a graphical user interface
(GUI). The chaos theory and random generation numbers are included in the algorithms to simulate the heterogeneity of grain
sizes and morphologies. |
