the chemical domain are not always known, unlike physical domains
such as thermal properties and vibrations, Hruby continued.
" [Chemical domain] tends to be much more difficult to characterize
and to understand until you really get that experience into that environment
- really what I'm talking about here are the chemical poisons, "
he said, adding that this hurdle also applies to battery-electric
solutions. " There's a chemical and an electrical component, and
there's an interface between those two. There's been great work and
effort characterizing that, but there's still many unknowns. "
Improvement opportunities
One area for improvement is cost. " When you have all these pieces of
software, each have their own licenses and they can each do something
great, you need them all, it ends up being very expensive overall, "
said ORNL's Chambon.
Cummins' Tickel agreed, adding that better communication among
the various simulation platforms is necessary. " Once you've invested,
you don't want to invest in two more tools or five more tools, " he
said. " The codes can talk to each other - everybody says they can,
but they don't [always]. "
Tickel said that FMI (Functional Mock-up Interface), an open standard
for exchanging dynamical simulation models between different
tools in a standardized format, and FMU (Functional Mock-up
Digital twin technology will reduce the need for physical
prototypes and result in fewer simulations as well, according to
an independent survey released by Altair.
Unit), a file that contains a simulation model adhering
to the FMI standard, help. " But we need more of that
interchangeability and data exchange, making it that
much easier, " he said. " That's going to help us, because
one location may be Abaqus, another might be
Ansys or whatever else. More standards on how
[tools] talk and work together is key. "
