Thermal Analysis

First of all, in a Thermal Analysis, a design is either heated up or cooled down and the temperature is then calculated. A popular example is an electronic assembly, because most all products nowadays are electronic, such as “smart” components or Internet of Things (IoT) devices. For even more insightful simulation, a thermal analysis is coupled with a structural analysis (Thermal Stress) or a Fluid Analysis (Conjugate Heat Transfer) to simulate multiple physics at the same time. Without having to actually build, test, and destroy an expensive prototype, thermal analysis can investigate many design changes, and validate decisions earlier. Typically Thermal Analyses solve very quickly, because there is only one variable to solve for: Temperature. As a result, a designer can try many “quick checks” during the progression of the design.

An Under Utilized Resource

Additionally, many FEA and CFD software include conjugate heat transfer automatically. When using FEA, the coefficient of thermal expansion is used to simulate the growth (or shrinking) of a solid as a result of adding (or removing) heat. When using CFD, the interface (boundary layer) between the solid and fluid volumes must contain a lot of detail, so convection is accurately simulated. In most cases, the affect of the heat transfer does not impact the flow. However, with Natural Convection, heat transfer and fluid flow are interdependent because the effect of hot air being less dense then cold air is taken into account.
