What’s New in Simcenter FLOEFD 2019

Simcenter FloEFD is a frontloading Computational Fluid Dynamics (CFD) simulation solution fully embedded in most available CAD software such as NX CAD, Solid Edge, Creo & Catia for designers. Frontloading CFD refers to the practice of moving CFD simulation early into the design process, enabling design engineers to evaluate design options and optimize product performance as well as reliability in the same CAD platform.

Simcenter FloEFD interface enables the user to validate the product design without any disruption and streamlining the workflow enabling engineers to assess the behavior of the design with multiple design options earlier to come up with the best that suits the demands of the customer and reduce design time by 40x.

Simcenter FloEFD 2019 – Features

Siemens comes out with regular releases, bug fixes, and new feature enhancements to provide more user-friendly interface with best in class and intelligent technology to meet the user expectations. Let’s look at what are the new features in Simcenter FloEFD 2019, so far:

Fan derating – Fans are run at a lower capacity by reducing their RPM, to increase their lifespan and reduce noise levels, while still achieving thermal cooling requirements. Also known as derating factor, a thermal-derating box can be calibrated to obtain uniform airflow, reducing the fan curve.

Logical Expressions in Formula Dependency –Dependencies are made u (up) of actions and triggers depending upon coordinates, time and monitor parameters. Each dependency defines a list of actions which is possible using conditional logic and Boolean expressions such as IF, AND, OR, XOR, NOT, > (more than), < (less than), = (equal two).
For example, the value of a heat source can be set depending on two different temperature sensors (also known as temperature goals) so that the power is reduced depending on the temperature at either one or another sensor.

Increased Altitude Problems – To conduct ‘what if’ and optimization analysis, you need the right altitude setting. The atmospheric pressure and temperature can be defined by setting the Altitude.  The sum of temperature and temperature deviation gives the resulting temperature.

Adding More Rays for Radiation Sources – Additional rays can be added and launched from Monte Carlo radiation source only. The Monte Carlo radiation model enables you to use the ray visualization to see how rays bounce starting at one surface ending at another or how they reach a specific surface. This significantly saves calculation time and enables radiation freezing automatically.

Network Assembly – Node power can now be dependent on Temperature.

Modeling Heat transfer Through Porous Media – A heat source or sink works better in porous media. The heat transfer in the porous media gives a very high value of the heat transfer performance and depicts a gas-liquid cross-flow heat exchanger. The efficiency of the heat sink model using sintered porous material for cooling high-power mini-devices is the actual fluid while hot liquid flowing perpendicularly is a virtual fluid and just adds heat to the system.

Radiation scattering – Scattering of radiation in solid bodies can now be done by specifying the scattering coefficient and scattering anisotropy under Radiation Properties for the Solid Material in the Engineering Database.

Radiation source – Radiation has a significant effect on the velocity field and temperature distribution. The increase in either the radiation parameter or porosity parameter makes the wall temperature decreases. The radiation source can now depend on coordinates and time.

Defining Vapor diffusion coefficient – The vapor diffusion coefficient of a membrane is dependent on temperature.

Dependency – Developed to simulate and study turbulent flows, Simcenter FloEFD can predict them based on a coordinate dependency for turbulent parameters, pressure, and components of velocity and Mach number. These have been added for more detailed definitions of these parameters.
The improved separate mode in surface parameters – Surface parameter do not have to be calculated on the geometry surface. They can now be calculated in section plane. Earlier in order to measure integral surface parameters, you had to create an auxiliary body and disable it before the calculation. Moreover, if there were many components using the same material, different contours were named equally. Now contours are named uniquely by the names of the components. All you need to do is, just select a plane, planar face or curve to calculate local and integral parameters in the section.

• Add from component – It is possible to add local mesh condition from a component.
• Design of experiments – Response Surface viewer has now a chart for the objective function.
• Free surface –Air compression is taken into account.

Conclusion

Simcenter FloEFD is an efficient frontloading CFD analysis solution for designers made available within most of the CAD platforms. In other words, you use the same user interface for design and analysis thereby rendering CFD simply as an extension of your design process.

Simcenter FloEFD enables you to gain insight into your product performance & reliability by optimizing complex fluid flow and heat transfer effects on your design directly in your CAD platform, while also reducing physical prototyping and development costs, without time or material penalties.

Experience streamlined workflows, faster results, and increased productivity with FloEFD.
