37  We want to define a rectangular domain of width $5 km$ and depth $6 km$ below the surface of the Earth. The domain is subject to a few conditions. The temperature is known at the surface and the basement has a known heat flux. Each side of the domain is insulated and the aim is to calculate the final temperature distribution.  We want to define a rectangular domain of width $5 km$ and depth $6 km$ below the surface of the Earth.

241  The curve defining our clinal structure is approximately located in the middle of the domain and has a sinusoidal shape. We define the curve by generating points at discrete intervals; $51$ in this case, and then create a smooth curve through the points using the \verb Spline()  function.  The curve defining our clinal structure is located approximately in the middle of the domain and has a sinusoidal shape.
