The processes described by the parabolic type equations are not periodic (why?!). Therefore the animation cyclically repeats (with a small pause between sessions).

The temperatures on the ends of the rod are constant (equal to zero). Pay attention to the quick decay of the high-frequency components. | |||
The rod borders are thermally isolated. | |||
