DescriptionPre- and post-processing is still a major problem in
industrial computational fluid dynamics (CFD). With the
rapid development of computers, physical solvers are
getting faster, while pre- remains slow because it's
mainly a serial process. A methodology using MPI+OpenMP
hybrid parallelization has been proposed to eliminate
the manual work required during pre-processing for
correcting the surface imperfections of CAD data.
Compared to the rapidly increasing amount of data in
recent years, the speed-up of visualization is
insufficient. We address this limitation of post- by
adapting the in-situ visualization to parallelize the
post-processing using libsim (Visit) library. The
performance of pre-/post- processing is investigated in
this work, and we show that the pre-processing time has
been reduced from several days in the conventional
framework to order of minutes. The post-processing time
has been reduced seconds order per frame, and
approximately 30% increase of computational time was
observed in vehicle aerodynamics cases.
