Benefits of Thermal Simulation


"Using the quick and accurate thermal simulation features in 6SigmaET, we were able to cut our modeling time by 30%"
William Villers, CTO & Director of Engineering, TEN TECH LLC


Across the electronics industry, competition to release new products quickly has created a need for ever-shorter design and development cycles. Today, you need to reduce and manage risk at every phase of product design to avoid expensive failures and redesigns in the later stages.

Thermal simulation gives you a unique visual representation of the temperature and airflow inside the equipment. This insight allows you to make better engineering decisions, enabling you to design a cooling system that balances performance and cost.



Thermal simulation can be used at any stage of thermal design. However, it is most effective when used early.

Simulation can show you a range of chassis designs and proposed component layouts on the PCB. This allows you to understand the type of heatsink design required, and helps you to size the right fan (where applicable). It also helps EEs and MEs communicate with you in a more meaningful way, setting the stage for more cooperative product development.

With unlimited space, power and budget, it’s easy to design a cooling system for almost any equipment. However, in reality, all equipment has rigid specifications: you need to reduce power requirements, system weight and cost without compromising performance and reliability.

Thermal simulation allows you to experiment with optimization – such as modifying heatsink geometry or reducing fan speeds – in a virtual environment. This is faster, cheaper and safer than physical experimentation and measurement.


No design is complete without using prototypes to test the system, but how many are needed to find the right solution?

If problems are discovered, how long will the project be delayed while you fix them? With any late-stage design modifications, there are significant costs required to fix issues. These issues can be identified earlier if thermal simulation is used as part of the design process, reducing the number of prototypes needed for verification.

Using Thermal Simulation Saves You Time and Money

Thermal simulation cuts time and cost during the engineering design process by reducing the number of design iterations and identifying issues early. Cutting your time to market in this way also increases your competitive edge.

The optimizations made possible by simulation can also reduce the parts cost, noise level and size of the equipment, making it more desirable to your customers.
