Approach on simulation of solidification and shrinkage of gravity cast salt cores

In this work, a toolchain for the solidification and the shrinkage of cast salt cores used in high-pressure die casting is implemented in the open-source computational fluid dynamics (CFD) library FOAM-extend to evaluate the displacements resulting from residual stresses. The toolchain consists of three stages, which first calculate the phase change, then generate the residual temperatures and finally calculate the residual stresses resulting in displacements. The calculated displacements were compared to 3D-Scans of casting trials of simple test geometries. The comparison showed acceptable agreement for engineering purposes.
