[SY-I12] A Parallel Algorithm for High Resolution 3D Phase Field Simulations of Polycrystalline Solidification
We deal with numerical solution of a three-dimensional phase field model of solidification in single component anisotropic materials. In this contribution, we extend the model by crystal orientation transformation. A robust algorithm is then developed to simulate the growth of multiple grains with an arbitrary number of random crystallographic orientations and a fully resolved 3D dendritic geometry. In the first part, the model and the hybrid parallel implementation of the algorithms are explained. The second part is devoted to demonstrating the effect of mesh-related numerical anisotropy, investigation of the parallel efficiency, and the simulations of complex polycrystalline solidification on very fine meshes.
