[aspect-devel] Boundary Temperature

[FELIPE ORELLANA ROVIROSA]

 Hi all,

    I am trying to prescribe a function as the temperature boundary
condition, say inhomogeneous Dirichlet for the heat equation.

    I guess the syntax must be rather simple, but I am not getting it. I
have browsed and browsed examples unsuccessfully.

  I am trying things of this kind:

   subsection Model settings
  set Fixed temperature boundary indicators   = top
  set prescribed temperature boundary indicators = bottom: function

subsection Boundary Temperature model
  subsection Function
    set Variable names      = x,y
    set Function constants  =
    set Function expression = 1500  + 200*exp(-(16/(2.5e11))*( (x-6e5)^2 +
(y-4e5)^2 )
 end
end

 and when trying to run it, the system complains:
 Line <91> of file <input string>: No such entry was declared:
    prescribed temperature boundary indicators
    <Present subsection:
        subsection Model settings

''invalid input parameter file''.

hope someone can help me,
cheers,
Felipe
