Core Software

Thermal Analysis Solutions for Complex Mechanical Systems

We verify components meet requirements early in the design cycle, saving you costly and time-consuming prototype iterations.

What is Thermal Analysis?

Thermal analysis is a set of techniques used to study and understand the behavior of materials and systems in response to changes in temperature over time. It involves the measurement and analysis of thermal properties and how they change as temperature varies.
.

Why Use Thermal Analysis?

Thermal Analysis is used to understand and predict how heat is distributed and managed within a system or component. Thermal analysis is important when materials are exposed to high temperatures, when heat is being dissipated, or when a process requires a change in temperature. Machines, products, and devices utilizing electrical components require thermal analysis to evaluate and compare different cooling solutions (such as air cooling, liquid cooling, or heat sinks) of the electrical system.
