The numerical investigation of continuous casting requires more than just one simulation technique. In continuous casting, liquid metal is continuously poured into a mould while the starting head is slowly moved downwards, which results in a growing metal ingot. Though, the ingot’s outer surface is solidified after the mould, its inside core is still a mixture of liquid and mushy phases. This mixture of physical states requires different numerical schemes to describe the constitutive behaviour and relation. While the liquid region is described in the Eulerian approach, the solid is well described in the Lagrangian approach. Commonly the finite volume method is chosen for the Eulerian and the finite element method for the Lagrangian perspective. Consequently, it is logical to combine a CFD solver with a FEM solver for an ideal numerical representation of the continuous casting process. The coupling of two different solvers communicating in two different programming languages - in the present work OpenFOAM and LS-DYNA - is not an easy task. However, preCICE enables the coupling of the different solvers with a minimum of intrusive functions. The present work deals with the first step towards the coupled simulation routine for the continuous casting process. A first basic simulation of a simple plate was setup consisting of OpenFOAM for the Eulerian approach and LS-DYNA for the Lagrangian approach. OpenFOAM calculates the temperature field due to time-dependent boundary conditions, while the mechanical LS-DYNA solver calculates resulting strains and stresses considering thermal strain. The aim of this simulation was to develop and test the preCICE adapter for LS-DYNA, as the adapter for OpenFOAM is already available and ready to use. The mapping techniques of preCICE did manage to achieve good energy conservation results. The first results showed a good correlation especially in the middle of the domain. The difference at the plates’ ends between the two different methods defined the next steps for the coupling
