Simcenter FLOEFD

3D CFD Analysis inside your CAD software in the early stages of the project

Simcenter FLOEFD helps you to shorten your design cycle time and get your products to market faster, moving 3D CFD analysis and simulation earlier in the design process.

Since Simcenter FLOEFD is fully integrated into your 3D mechanical CAD (NX, Solid Edge, Creo, Catia, and Solidworks), you can easily explore the design space to create better designs, faster.

Why choose Simcenter FLOEFD for 3D CFD Analysis?

It is the only CFD solution for design engineers

With Simcenter FLOEFD, design engineers can take care of fluid dynamics and thermal simulation directly. Siemens’s tool has a very fast learning curve and does not require CFD experts to build accurate models. It is the first tool to bridge the gap from R&D usage to mass market engineering simulation software.

Frontloading CFD improves products and competitiveness

Simcenter FLOEFD allows you to conduct simulation and 3D CFD Analysis early and often in the design cycle so that you can choose among different alternatives and arrive early on the market with the best solution for both you and your customers.

It is integrated with mechanical CAD. Yes, just what you use!

You can use Simcenter FLOEFD for your 3D CFD Analysis directly in NX, Creo, CATIA V5, or Solid Edge in order to explore the full potential of your ideas quickly, without disrupting your design process. Any barrier between MCAD and CFD simulation is overcome!

It is designed specifically for Electronics Design

Simcenter FLOEFD includes several modules dedicated to the Electronics industry such as the LED module, Battery module, and the FLOEDA Bridge. The LED Module allows you to build an accurate thermal simulation of LEDs thanks to an innovative optical-thermal model of LEDs. The FLOEDA Bridge imports PCB designs directly from your ECAD system (PADS, Xpedition, Altium, etc) via the ODB ++ format. It also includes several libraries of electronic components, fans, heatsinks ready to be used.

The Advantages of Frontloading CFD

Frontloading CFD is the practice of moving CFD simulation early into the design process where it can help identify trends and guide the designer in creating better designs. By frontloading CFD simulation through CAD-embedded software the user can take advantage of a highly efficient and fast workflow and fully explore the design space to create more reliable designs, faster. And this is exactly where FLOEFD fits into your design workflow.

Siemens‘ customers such as Porsche, Valeo, and Renault rely heavily on the concept of frontloading CFD for their design teams. In addition to the Automotive and Transportation sector, many other industries can benefit from frontloading CFD with FloEFD, such as Electronics and Semiconductors, Industrial Machinery, Lighting, Medical, Aerospace, and Defence, Energy, and Consumer Electronics.

Electromagnetics in Simcenter FLOEFDYou can now simulate Alternating Current and Electromagnetics (low frequency) effects. Enabling electromagnetics allows for increased accuracy of thermal simulations by taking into account Ohmicand iron (core) losses due to AC and electromagnetic phenomena such as proximity, skin effect, etc. An electromagnetics analysis is defined together with a CFD analysis and a CFD-EM co-simulation takes place by exchanging the power (Ohmicand iron losses) and temperature fields.

Structural finite element linear solver capabilities

Structural finite element linear solver capabilities in Simcenter FLOEFDSimcenter FLOEFD uses a finite element (FE) non-iterative solver for structural analysis. The range of analysis types in the FE solver includes: static response to loads, to thermal expansion and to enforced deformation, and also the determination of eigenvalues. Since the relationship between the load applied to an object and the response of the object is assumed linear, the set of linear equations is considered. A linear approach can be used when these assumptions are made:

  • Deformations are small and do not impact the calculation result; set of linear equations are based on non-deformed geometry
  • Temperature variation within the model is not considerable or material properties temperature dependency is not strong.
Modal frequency analysis

Modal frequency analysis (vibration analysis) with Simcenter FLOEFDAn available sub-type of structural analysis is Frequency analysis. Simcenter FLOEFD is capable of predicting eigenvalues of the non-loaded model and showing dimensionless deformation fields for each mode. The resulting frequency tables can be exported to Microsoft Excel manually or automatically with the Batch Results Processing tool.
