This paper reports on progress in the implementationof COMSOL Multiphysics 3.2 to model thermalstresses in a three-dimensional solidifying shell, asoccurs typically in the industrial continuous casting ofcopper, copper alloys and steel. Computer memory requirementsprohibit a direct 3D numerical simulation ofthe temperature and the stresses. Instead, we use the factthat casting geometries are usually slender to divide thecalculation into three steps that are each less memoryintensive:(i) heat transfer and solidification is simulatedusing an arbitrary Lagrangian-Eulerian model; (ii) thetemperature solution is used to solve the force equilibriumequations in generalised plane strain mode appropriatefor a moving body; (iii) this solution is used tocompute the accumulated stress and strain in the body.Comparison between an analytical solution and a numericalsolution, that requires the simultaneous use ofseveral of Comsol Multiphysics’ peripheral features, ispresented.
