   A box-shaped In-Form object is used for the specification
   of the initial (and unchanging) values of the material index,
   PRPS.

   The value assigned is 100, which corresponds to aluminium.

   The object is surrounded by air, and placed between a hot and a
   cold wall.

   The steady-state temperature distribution as influenced by
   conduction alone.
