The previously described functions define the specific problem. For the numerical computation of them a set of problem dependent subroutines in Fortran77 has to be provided by the user. They are collected in the file uspec.f.
Important note:
Parameters of the problem dependent subroutines
in the file uspec.f denoted by
``Ausgabe'' or ``Output'' have to be set on exit of the subroutine.
All other parameters which are not explicitly denoted
by ``Ausgabe'' or ``Output'' may not be changed
in a subroutine. Changing them will be harmful!
