Abstract A general governing equation for tracking the filling free surface during compression molding is derived. From this equation, with appropriate choice of parameters, a time‐implicit fixed grid solution and a time‐implicit deforming grid solution are obtained. Numerical results of several test problems reveal that both solutions reach the same level of accuracy. The fixed grid scheme, however, is more robust and can solve problem with complex geometrical features.
