This paper presents a compression molding filling simulation of thin parts of otherwise arbitrary shape, including inserts in the mold cavity, and mold cavities with multiple charges. The simulation predicts pressure and velocity fields and position of flow fronts during filling, as well as the location of knit lines in the molded part. The program automatically generates the finite element meshes, allowing it to run without user interaction. Much of the discussion centers around sheet molding compound (SMC) and related materials, but the model is not restricted to this class of materials.
