Abstract: A computer-implemented method and corresponding computer-based system perform a computer simulation, via at least one processor, of a filling stage of an injection molding process that fills a part cavity of a part with material over a filling time. The simulation is based on a boundary integration method and a mesh model. The mesh model represents the part cavity. The simulation computes a part thickness distribution of the part based on the mesh model. The boundary integration method computes velocity and temperature at a flow front of the material over the part thickness distribution computed and determines advancement of the flow front based on the velocity and temperature computed. The simulation outputs, via the processor, at least one indication of behavior of the injection molding process determined based on the simulation. The simulation transpires in real-time relative to the filling time.
