### Abstract

This study sought to investigate the use of a
high-performance computing environment to efficiently
automate some of the early steps in the design process.
The idea was to manipulate commercially available
software to automate the running and results tabulation
of a large number of topology optimizations. This was
achieved by creating a finite element model of the chosen
case study (genset base frame), creating superelements
for large, complex components that were attached (engine
and generator), preparing a topology optimization model,
generating shape variables that altered the length, width
and height of the design space, and launching a design of
experiments on a computing cluster so that 64 variations
of the topology optimization were run. Upon completion of
each optimization run, the DOE automatically launched a
program to interpret the results in several different
ways, and then subsequently submitted the new design for
reanalysis based on the initial design criteria. The
results of the reanalysis were automatically tabulated
for easy comparison of designs. The DOE set-up was also
flexible enough to allow for additional topology
optimization results interpretation and reanalysis after
the initial runs were completed. The final result was
hundreds of designs from which it was easy to select
those which were most able to achieve the design goals.
