Abstract:
The simulation of the phase transition for solidification of Fe-C alloy with the Cellular Automata (CA) method interfaced with the hp-adaptive Finite Element Method (FEM) for the non-stationary heat and mass transport problems is presented in the paper. The computational domain is discretized by the uniform grid for the CA and a sequence of non uniform meshes for the self-adaptive hp-FEM. The rule-based CA model is responsible for the simulation of the grow of the new phase within the Fe-C alloy. The self-adaptive hp-FEM generates a sequence of meshes delivering exponential convergence of the numerical error with respect to the mesh size (CPU time). The solution from the previous time step as well as material data from the CA grid are projected to the current self-adaptive hp-FEM. The detailed description of the developed approach as well as the examples of numerical simulations are presented and discussed in the paper.
