In this work we present a ΓΏnite element formulation to simulate the ΓΏlling of thin moulds. The model has as starting point a 3-D approach using either div-stable elements, such as the Q2=P1 element (tri-quadratic velocities and piecewise linear, discontinuous pressures) or stabilized ΓΏnite element f

Finite element algorithms are presented for the entire casting process from the mould ΓΏlling stage to the prediction of the ΓΏnal distorted shape. The various algorithms available in the literature for solidiΓΏcation modelling are discussed in detail. Special emphasis is given to the coupling of the s
The traditional Lagrangian and Eulerian formulations in finite elements posses some inherent difficulties when used in simulation of metal-forming processes or general finite strain problems. A more general method of formulation, the Arbitrary Lagrangian-Eulerian (ALE), is developed to overcome such
