Abstract: In the field of modelling of solidification processes, there is much debate between the various numerical techniques used to solve the conservation equations. The arguments are very often based on the numerical technique itself (Finite Differences (FDM), Finite Volumes (FVM), Finite Elements (FEM), ldots). This paper shows that, more than the numerical technique, the issue is related to the enmeshment used: structured or unstructured meshes. The advantages versus inconveniences of both enmeshment types are discussed in the present contribution.
