Features & Benefits


Import. Solve. Display. It's that easy!

6SigmaET is the only CFD software for electronics cooling that is constantly expanding its list of features, enabling you to design, solve and analyze your thermal models faster than ever before. With its unparalleled feature set, 6SigmaET is quickly becoming thermal engineers' tool of choice for electronics thermal simulation.

Intelligent - Image


Built-in intelligent components know how they should behave, and are placed according to how they fit together with other objects. This means you can spend less time figuring out how to model your equipment, and more time refining your thermal simulation design.

Controller Controllers

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


Controller Altitude

6SigmaET can run simulations at different altitudes, which is essential for Aerospace and other industries.

Component Component Modeling

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

Component Multi-Fluid

Model liquid-cooled systems using intelligent objects such as cold plates, pumps, and cooling ducts.


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

GUI Modern User Interface

Utilize the GUI and simple ribbon system to build, solve, and analyze your model.

PCB PCB Modeling

Intelligent PCB objects allow you to quickly and accurately model PCBs.




Why start at the beginning when you can use existing engineering data? 6SigmaET is connected to your existing engineering design tools, so you can import power maps and mechanical CAD (such as IGES, STEP/STP and STL), along with ECAD data (including IDF, IDX, ODB++ and GERBER) directly into your model.

Library Centralized Libraries

Share objects, assemblies, or even whole models across an organization with centralized network libraries.


Library Import/Export MCAD & ECAD

Import CAD designs and export your 6SigmaET models in DWG format, or export model objects as STL files.

VersionTree Version Tree

Consolidate various designs and objects (PCBs, components etc.) in a singular tree, allowing for tighter integration between various models.

PowerImport Power Map Import

Import the power map of a component die to accurately model the power dissipation across it.

PCBImport PCB Data Import

Import PCB designs via IDF, IDX, XFL and Gerber file formats.


Automatic - Image



6SigmaET automatically checks for collision and modeling errors, allowing you to address problems as they appear. Additionally, the automatic, object-based gridding feature allows you to set up and solve thermal simulation models with ease.

Reporting Automatic Reporting

Fully customizable reporting allows you to communicate, compare and analyze your simulation results.


MultiView Compare Models Window

Compare results from different versions using the compare models window to identify the best solution.

Batch Batch Solve

Queue up and simulate multiple models using the batch queue, then share those simulations among your engineers.

Grid Automatic Unstructured Gridding

Our object-based gridding feature determines the best grid for the simulation. Just click the Solve button and the grid is automatically generated.




Engineers can’t wait days for a thermal simulation to solve - you need the results to make decisions about every aspect of your thermal design quickly. 6SigmaET’s powerful unstructured CFD solver is capable of solving even the most complex models in a fraction of the time compared to other tools in the market.

“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.”

Norbert Engleberts

Director, OTS

“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

“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

“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.”

Saket Karajgikar

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

“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.”
