A full filling and solidification simulation of the MCWASP 7 casting has been carried out using the commercial finite element (FE) analysis codes LS-DYNA3D and FIDAP. The two codes were used to carry out back-to-back analysis of the mould filling. Both codes track the free surface and predict filling times. LS-DYNA3D has been used both for the filling simulation and to carry out a coupled thermal and stress analysis of the casting during solidification, predicting cooling rates, residual stresses and as-cast shape. The methodology used and details of the FE models are summarized. Results are presented for comparison with the casting trial data (x-rays of filling and thermocouple data).
