The stress-from-heat problem involves a tube in a ceramic block. One surface of the block is uniformly heated. A first step of this sequential multiphysics analysis solves for the velocity profile.

Fourier's well-known heat equation, introduced in 1822, describes how temperature changes in space and time when heat flows through a material. In general, this formulation works well to describe heat ...

When we think about heat traveling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump ...
