Yearly temperature variation beneath a slab on the ground. The outdoor temperatures has a maximum of +23 °C and a minimum of -7 °C, see function 1 defined as below

Sinusoidal variation for outdoor temperature

The Movie Maker captures graphical output data, such as temperatures, isotherms, and heat flows and makes a standard AVI-file.
