Electrophoretic Deposition (EPD) coating is one of
the key applications in automotive manufacturing. In the recent
years, tools based on Computational Fluid Dynamics (CFD)
have been utilized to simulate corresponding coating processes.
However, the complex data used in this application frequently
brings standard CFD applications to its limits. For that purpose, a
CFD-based tool named ALSIM has been proposed, which employs
a unique volumetric decomposition method that addresses these
problems. However, certain characteristics of this methodology
yield drawbacks for the typical process used in this application - resulting in large execution times. In this work, we present a
parallel scheme for this application which addresses these shortcomings.
To this end, two layers of parallelism are introduced.
Both are implemented by employing OpenMP, allowing for the
execution on shared memory parallel architectures. Experimental
evaluations confirm the scalability and efficiency of the proposed
methods. The simulation time of a typical use case in the
automotive industry could be reduced from almost 6 days to
13 hours when employing 16 processing cores.
