Polymer molding simulation is usually done by a numerical analysis method called finite element analysis. This method rests on very heavy computations which do not always give the desired results. We present a new approach to simulate fluid injection in matrices, based on a macro analysis of the propagation front during the molding process. We introduce a model combining morphological and geodesic dilation of the propagation front with region growing techniques, by associationg a structural dilation shape to each boundary point at a given time. The implementation uses "propagation maps" and leads to an efficient method, allowing elaborated simulations. We give some resultss in 2D and in 3D demonstrating the ability of our model to simulate complex processes. We also present a method to build the propagation maps from a limited number of known steps.
