Schifko, M., Steiner, H., Fellhofer, D., Song, X. et al., "Transient Dip Paint Simulation of Entire Car Bodies within One Day," SAE Int. J. Mater. Manf. 8(2):523-533, 2015, doi:10.4271/2015-01-0731.
The development of entire car bodies benefits from simulations, especially if they are performed at an early stage of development. Simulations lower the costs for required car body modifications. This paper focuses on dip painting simulation and describes the simulation process by detecting badly painted areas and liquid carry overs. A new hydrodynamic method has been benchmarked to CFD and real-life results. Results will be shown together with case examples. The solver is similar to, and as accurate as, standard CFD solvers; it is faster in its computation speed by a factor of at least 1000. The electrophoretic deposition (ELPO) of an entire car body can be simulated overnight with ALSIM. How is this possible? This paper points out the reason for all of this.
