Example Models

Free Convection in a Light BulbFree Convection in a Light Bulb

This model treats the free convection of argon gas within a light bulb. It shows the coupling of heat transport (conduction, radiation and convection) to momentum transport (non-isothermal flow) induced by density variations caused by...

Continuous CastingContinuous Casting

This example models the casting process of a metal rod from melted to solid state using the Non-Isothermal Flow multiphysics interface, which combines heat transfer and fluid flow. The model describes the fluid and solid flow and heat...

Friction Stir Welding of an Aluminum PlateFriction Stir Welding of an Aluminum Plate

In friction stir welding, a rotating tool moves along the weld joint and melts the aluminum through the generation of friction heat. The tool’s rotation stirs the melted aluminum such that the two plates are joined. In this model,...

Hepatic Tumor AblationHepatic Tumor Ablation

One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe...

Heat Transfer in a Surface-Mount Package for a Silicon ChipHeat Transfer in a Surface-Mount Package for a Silicon Chip

All integrated circuits—especially high-speed devices—produce heat. In today’s dense electronic system layouts heat sources are many times placed close to heat-sensitive ICs. Designers of printed-circuit boards often need to...

Convective Cooling of a Potcore InductorConvective Cooling of a Potcore Inductor

The inductor is a common component in a variety of electrical devices. Its applications include power transformation and measurements, and it can also be used together with capacitors to create oscillators. In small devices with many...

Fully-coupled Physics with Joule Heating, CFD and Chemical ReactionsFully-coupled Physics with Joule Heating, CFD and Chemical Reactions

In this example, a fluid carrying several chemical components is pumped into a detector compartment. A wire in the center of the detector is heated through Joule heating, which is supposed to detect changes in density through convective...
