Qfin4
Electronics Cooling Design, Analysis, and Optimization Tool

Quick and easy 3D modeling of electronics systems
Built-in components representing all typical parts of a system, including heat sinks, fans, openings, grilles, heat pipes, plates, and many more. Each component has a step-by-step wizard allowing quick and intuitive creation, and can be modified at any time via its own property panel.
Fast combined flow and conduction solutions
Qfin uses a novel systems CFD approach to quickly and accurately solve the combined momentum, continuity, and energy equations. The solver is very fast and very stable, typically taking only seconds to calculate a solution. It is also very accurate for transitional flow, and can handle transient calculations efficiently. These properties make Qfin an ideal design and optimization tool.
Ideal for design and optimization
Every component in Qfin4 is already fully parameterized to allow for quick design-analysis-design cycles. The software also includes an easy to use parameterized trial solver and a sophisticated design optimizer.
