Celsius EC Solver calculates airflow, thermal conduction, and radiation in electronics enclosures — using fans, heatsinks, heat pipes, and cold plates as ready-to-use objects, directly based on your own CAD geometry.

The challenge
The solution
HOW IT WORKS
Over a hundred ready-to-use objects cover the components actually present in an electronic product. A board is a board, and a fan is a fan — not a geometry that has to be defined from scratch.
The MLUS mesh is generated automatically based on the objects, placing resolution where it matters. This is typically the most time-consuming step in a general CFD tool.
MCAD from Creo, SolidWorks, and CATIA, and PCB data via ODB++ or IPC-2581. The model does not require simplification before calculation.
VALUE
Ready-to-use objects, automated meshing, and the underlying physics that determine whether a product can cool itself effectively.
What takes time in thermal analysis is rarely the solver run itself. It is building the model.
Heat leaves an enclosure via multiple paths simultaneously, and all three must be calculated together.
Meshing is where thermal analysis most often stalls for engineers who do not perform it every day.
The enclosure already exists in MCAD, and the board exists in ECAD. Both must be directly usable.
The initial calculation answers a single question. The true value lies in exploring further scenarios.
Implementation
An enclosure where you already have known thermal data is the best starting point. The model can be verified against empirical measurements from day one.
How detailed the board needs to be, which components are critical, and when simplification is appropriate. These decisions determine both run time and reliability, and we provide technical guidance throughout.
You get direct access to specialists with practical experience in CFD and thermal management. Questions about a specific model receive concrete answers during an active project.

A short conversation is usually enough to determine whether EC Solver is the right fit. No sales pitch. No pressure. Just a technical discussion about the enclosures and power dissipation requirements of your products.
FAQ
Both calculate flow and heat transfer. EC Solver is built for electronics cooling, where fans, heat sinks, and boards exist as ready-made objects, and where meshing is automated. Fidelity CFD is built for general flow — turbomachinery, marine applications, and aerodynamics — where fine control over the mesh matters most. If the task involves an electronics enclosure, EC Solver is typically the most direct route.
No, not to get started. The model is built using pre-defined objects, and meshing is automated. However, the results still need to be evaluated by someone who understands the model's inputs — and that is where we can assist.
Yes. EC Solver became part of Cadence with the acquisition of Future Facilities in 2022 and was previously known as 6SigmaET. It is the same tool, and some customers still know it by its former name.
Yes, and that is often the right approach. EC Solver covers the airflow and enclosure, while Thermal Solver covers the chip and package. Both are part of the same platform, Celsius Studio.
