[en] The microstructural features observed on some DyBa2Cu3O7-x, samples show that kinetic considerations are as important as thermodynamic ones. In order to compute and characterize the kinetic growth front of 123-(RE)BCO compounds, we have introduced an anisotropic growth direction into a simple two-dimensional growth model: the Eden model defined on a square lattice. The presence of 211 particles has been also considered. The simulated patterns in the ab and ac planes agree with observations and contribute to a more comprehensive model of the kinetic of the growth front near 211 particles.
