PLM
enabled CFD
Everywhere you look in engineering today, two acronyms abound: PLM and PDM. Whereas CAD companies are screaming these buzzwords (and the principles behind them) from the rooftops, CFD vendors are noticeably less vocal in their endorsement. It's not that CFD vendors think that PLM is unimportant; it's just that - with one major exception - their software solutions don't fit comfortably within the PLM framework.
PLM stands for product lifecycle management. It is describes a business strategy in which an organization's products are digitally managed from conception, through maturity, to eventual retirement. PLM is a huge concept that is sometimes difficult to comprehend in its entirety. One of its critical functions is to remove the barriers between the people who design the products and those who build, sell and support their use. Implemented successfully, it reduces time-to-market by streamlining design and reducing production costs. Put simply, PLM is the future of product engineering.
One
of the central tenets of the PLM philosophy is that all of the CAE
data for a product should be stored in a central location - shared
by all company functions, customers and suppliers. Every PLM strategy
must, therefore, be underpinned by a Product Data Management (PDM)
system. PDM is so important to the concept of PLM that the two terms
are often (incorrectly) used interchangeably. PDM is the essential
system for managing CAE (and especially CAD) data. Every revision
to the individual components that make up a product (and revisions
to the way in which they all fit together into assemblies) is tracked
and recorded in a central repository of data.
How
should CAE tools, such as CFD, be used in the brave new world of
PLM? Since the viability of a specific design is often determined
by the CAE tools being used, and since the CAE results often drive
the changes in those designs, it is critical to PLM that the CAE
set-up and results are stored within the PDM system. Herein lies
the problem for the majority of commercial CFD vendors: PDM systems
rely on a concept known as " associativity". In order
to be stored within a PDM system every CFD solution needs to be
intrinsically linked to a specific revision of a CAD model (or assembly).
While other CFD vendors claim that their products are "CADintegrated", all of them rely on some form of translation between the CAD model and the CFD package. Translation kills the associativity between CAD and CFD. Whether the translation is explicit (as in the case where you import your CAD through a " wizard") or implicit (where the CFD package is launched from within the CAD system), the very act of translation breaks the association, the CFD solution become disassociated with the CAD model.
CD-adapco's method of CAD-integration is different however. All of our CFD products are "CAD-embedded". CAD-embedded means more than embedding the CFD solver into the CAD package, it means that all of the settings required to set-up the CFD solution are stored within the CAD model itself. When the model is checked back into the PDM system, the model settings are stored along with a link to the solution data. If the CAD model is subsequently revised then the solution can be updated at the click of a button. If a downstream user retrieves the model from the PDM system, both the CFD solution and (as importantly) the way in which the CFD calculation was performed will be retrieved.
By developing the only CFD process that does not require translation, CD-adapco's products maintain associativity between CAD and CFD solution. Associativity is critical to PDM and to the wider concept of PLM, and to date, CD-adapco is the only company to offer truly PLM-enabled CFD. CFD’s destiny to become a central player.
