Multiple (Conflicting) Design Objectives


Why Aren’t More Companies Doing Multiphysics Simulations?

It’s too hard and complex.

We use other products and/or our own

codes for the other physics. We don’t really need it.

Single physics is adequate.

We have physics-specific engineering groups that

don’t work together.

Multiphysics isn’t accurate enough or practical

for real engineering work.

We don’t have expertise in multiphysics or in the

other physics.

Price Induction feed back

- No accurate results (more than 30% VS physical testing) - No dedicate tools for turbomachinery

- a lot of manual work - 4 months to run the CFD analysis

- Poor link between CD-Adapco and Dassault The feedback from Price Induction is that Dassault & CD-Adapco do no invest a lot in FSI benchmark because the link between Star and Abaqus is not mature and it’s time consuming for them

- Good CFD results but reuse for FEA still painful/complex

- results close to physical tests (CFD) - Ease of use for mapping CFD results on structure parts - Complete workflow for turbomachinery - Good scale up with HPC Pack - Excellent technical support :

- Excellent interaction during the benchmark - Help from ANSYS to define the best hardware solution

WEG: » The largest Latin American electric motor manufacturer

» Produces electric motors, generators, transformers and drives

» A local player who wants to be a global competitor

» Historically, they have been thought of as a low cost & lower quality

alternative to the major global players like Siemens, GE and ABB.

» In 2011 they expanded their global presence by acquiring Electric Machinery, an American company, from GE/Converteam.

» Up until 2012 WEG used simulation primarily for mechanical validation, now the perform over 800 simulations a month.

SUCCES STORIES - WEG

WEG was using FLUX for Motor Design. After a comprehensive work (Thanks to Paul Larsen) we got the same results as their measurements and slightly better than FLUX

Measur.

This just proves that our solution is as good as FLUX. So why would WEG switch from FLUX to ANSYS Maxwell?

FLUX Displacement on WEG Motors


SUCCES STORIES - WEG

The answer is MULTIPHYSICS INTEGRATION

ANSYS Proven Multiphysics Solution was the

key to displace FLUX at WEG Motors.

You can use data from those other products or data from experiments to include the effects of multiple physics

in your ANSYS simulations using advanced data transfer and exchange.

Using the deep, proven physics in the

You can easily train teams of engineers to use drag-and-drop multiphysics in

for real engineering work. Multiphysics is as accurate and

practical as the solvers in use. For example, you can use detailed

simulation or experimental results, instead of simplified assumptions to provide higher fidelity boundary and initial conditions. You probably have data today that could be integrated.

Multiphysics can also include 2-way co-

simulation, if you find the tight interaction of real world physics cannot

be ignored.




Basic engineering knowledge is required when performing any kind of

engineering simulation. Expertise specific to multiphysics is not necessary as long as a basic understanding of the various single physics exists. ANSYS

offers training in how to use our software for single and multiphysics

simulations.

We don’t really need it. Single physics is adequate.

Do you really think you can afford to ignore the effects of multiple physics in your simulations?

Multiphysics simulation is giving

our customers like you real insight into their products and
