Creo Dynamics [1] is a Swedish engineering company with core competence in fluid dynamics, acoustics and structural
dynamics. Creo Dynamics has broad experience from participating in national and international research programmes
focussing on the development of new emerging technologies for the automotive or aerospace industries. In the company,
experienced engineers develop and deliver simulation tools and procedures – often based on open source software [2] –
which are tailored towards specific needs and applications; this process always involves maintaining a conscious balance
between turn-around time and accuracy.
Creo Dynamics has recently undertaken a PRACE SHAPE project together with application experts from the KTH Royal
Institute of Technology. During the course of the project we developed templates and “recipes” for a range of tasks that are
involved in the automotive industry – such as automated handling of computer-aided design (CAD), parallel meshing,
solving and post-processing. These were all tailored towards a particular automotive application, namely the aerodynamics of
a heavy-duty semi-trailer. We also focused on parallel implementations and executions for large-scale simulations. In
addition to monitoring the efficiency of the processes (for meshing and solving run-time performance and scalability) and
identifying critical bottlenecks, we gave significant attention to pinpointing performance deficits in the processes so as to
give guidance for a further fine-tuning of the overall methodology.
