Kurzfassung Injection molding simulations are important tools for the development of new injection molds. Existing simulations mostly are numerical solvers based on the finite element method. These solvers are reliable and precise, but very computionally expensive even on simple part geometries. In this thesis, we aim to develop a faster injection molding simulation based on Graph Neural Networks (GNNs). Our approach learns a simulation as a composition of three functions: an encoder, a processor and a decoder. The encoder takes in a graph representation of a 3D geometry of a mold part and returns a numeric embedding of each node and edge in the graph. The processor updates the embeddings of each node multiple times based on its neighbors. The decoder then decodes the final embeddings of each node into physically meaningful variables, say, the fill time of the node. The envisioned GNN architecture has two interesting properties: (i) it is applicable to any kind of material, geometry and injection process parameters, and (ii) it works without a “time integrator”, i.e., it predicts the final result without intermediate steps. We plan to evaluate our architecture by its accuracy and runtime when predicting node properties. We further plan to interpret the learned GNNs from a physical perspective.
