What Makes 6SigmaET Unique?

6SigmaET is a thermal modeling tool that uses advanced computational fluid dynamics (CFD) to create accurate models of electronic equipment. Designed specifically for the electronics industry, our software ushers in unparalleled intelligence, automation and accuracy to help you meet your requirements and to overcome thermal design challenges.

Intelligent Intelligent

Built-in intelligent components know how they should behave, and are placed according to how they fit together with other objects.



Reproduce and experiment with sophisticated fan control systems using 6SigmaET. The controller object makes setting up a control system simple.

Component Modeling

Use the intelligent component modeling object to represent the thermal properties of a component using a simplified, 2R, Delphi or detailed representation.

PAC Study

Parametrically define a range of design options using the PAC study and quickly identify the best solution.

Consumer Electronics Consumer Electronics

Consumer electronics are getting smaller and more powerful creating new thermal challenges. The complete CAD geometry of a device and PCB design (using ECAD software) can be imported into 6SigmaET, reducing model creation time. Further time can be saved by using the 6SigmaET library, which can store parts for reuse in future projects.

Case Studies

  • Thanks to 6SigmaET we were able to create simulated models of our soldering processes and now predict the behaviour of PCBs inside our manufacturing processes. The software proved to be the best market choice due to its ability to import all BOSCH PCB and product files, by its simulation speed and for its flexibility to adapt to different simulation environments.

    Miguel Peixoto
    Process Engineer, BOSCH

  • 6SigmaET’s ability to import complex CAD files, coupled with its robust meshing and solving capabilities, significantly reduces our modeling time. We especially like the itemized results for heat distribution and the predefined thermal thresholds, which provide an easy snapshot of the simulation conditions.

    Manager, Thermal Design Group at Hyve Solutions

  • Over and above thermo-fluid modeling, 6SigmaET's library feature affords access to a PDM-like database for simulation models, making them accessible and shareable across the enterprise. This capability increases efficiencies, and brings consistency and reproducibility to our processes. The suite of features is user friendly, easy to use, and provides good resolution and accuracy in modeling.

    Martin Pais
    Fellow & Director, Motorola

  • Whether building up a model from scratch or utilizing the simplicity of the software’s import capabilities for CAD and IDF data...modeling times are significantly reduced. This has helped in quickly turning around solutions during the design cycle to verify the equipment’s ability to withstand the harshest environmental conditions we know it will most probably encounter.

    Pablo Zicone
    Mechanical Engineer, SELEX ES

  • Using the quick and accurate thermal simulation features in 6SigmaET, we were able to cut our modeling time by 30%. The platform’s high-performance, cloud based solving allowed us to scale without hardware limitations, giving us the opportunity to double the number of projects we can take on.

    William Villers
    CTO & Director of Engineering, TEN TECH LLC

  • A comprehensive standalone tool, 6SigmaET doesn’t need additional MCAD software for data entry, which means it is especially straightforward to use. The software is fast, fits our thermal modeling needs perfectly, and experimental testing in our laboratories has proven that the simulation results predict component temperatures with accuracy.
