Hi!

Mathematica doesn't like to numerically solve the border value problem

a T"[x] + b T[x]^4 + ... == 0, T[-hheight] == Troom, T[hheight] == Troom

This equation describes the equilibrium temperature distribution (with
thermal conductivity and radiation) in one dimension, where the ends are
fixed to room (or any other) temperature. What can I do to get a
solution?
