A stabilized hybrid FE/FV method applied to fluid flow in mold filling
Keywords:
casting processes, incompressible flow, pressure stabilization, finite volumes, stabilized finite element methods, MINI elementAbstract
Modern casting processes allow the precise production of parts with complex shapes. Numerical simulation increasingly becomes an important tool aiding design and production. A finite element method using finite volume principles is described. A new adaptive stabilization based either on bubble functions or a Petrov-Galerkin method is elaborated. Then, a new stabilization scheme, named FF-VOF, is presented to describe the free surface evolution during mold filling. Finally, the developed method is applied to the mold filling benchmark defined at the 7th Conference on Modeling of Casting, Welding and Advanced Solidification Processes.
