This work includes the development of computational fluid dynamic (CFD) and finite element analysis (FEA) models to investigate fluid flow , solidification, and stress in the shell within the mold during continuous casting. The flow and solidification simulation is validated using breakout shell measurements provided by an industrial collaborator. The shell can be obtained by the solidification model and used in a FEA stress model. The stress model was validated by former research related to stress within a solidifying body presented by Koric and Thomas. The work also includes the application of these two models with a transient solidification model and a carbon percentage investigation on both solidification and deformation.
