Effective CAE Process Using HyperWorks and TECOSIM Tools
Dámaso López Ruiz, Tecosim
The global economic crisis along with increasing global and
local market competition is pushing carmakers and suppliers
to reduce development costs. At the same time, strict government
regulations, new consumers’ requirements and rating
criteria also need to be fulfilled. Today,
the FE-Method is state of the art for almost every carmaker
in order to reduce
development costs and time to market, while
at the same time improving product quality. In order to be
able to reach and
maintain the pole position in the ever increasing
competition it is nowadays - more than ever - extremely necessary
to have
a reliable CAE process.
A new full FE model build up based on CAD data
takes between a few weeks and a couple of months,
depending on the complexity of the FE model,
the CAE engineers’ know-how,
CAE tools, etc. One full crash model calculation (for instance:
Front USNCAP) normally takes between 8 and 16 hours, depending
on the hardware and software used, the elements' quality,
etc. However, its post processing including the result interpretation
takes only a few hours. By comparing these three necessary
development steps, it is obvious that the first step “FE
model build up” slows down the entire process – that's
why it is so important to rely on a well defined
and effective CAE process.
This TECOSIM process is based on several years
of CAE experiences along with Altair solutions.
It uses HyperWorks (HyperMesh, HyperGraph,
HyperView, etc.) in combination with
TECOSIM tools (TEC|ODM, TEC|WORX, TEC|CHECK,
TEC|IDA, etc.) providing TECOSIM with a very
effective CAE process and helping
us to become the best partner for simulation.
HyperWorks and TECOSIM tools’ modular principle provides
these tools with a high level of flexibility to be easily
coupled to almost any existing development process worldwide.
