Summary

Heat conduction equation \frac{\partial T}{\partial t} = \Delta T will be solved until 3 seconds later.

For boundary conditions, temperature is fixed at 273 K for patch2 (red part) and 573 K for patch4 (blue part). All other boundaries are set to zero gradient.

From the calculation results, we can see how the temperature is conducted.

Commands
