Abstract
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 parallel implementation of the algorithms are explained. The second part is devoted to demonstrating the effect of meshrelated numerical anisotropy and the simulations of complex polycrystalline solidification on very fine meshes. [ABSTRACT FROM AUTHOR]
