I would like to know if Mathematica can solve a nonlinear ODE Boundary
Value Problem that arose from a physical model.
It is a 2nd order equation with values for the 1st derivatives at both
boundaries AND an unknown value for the 2nd derivative evaluated at
one of the boundaries as a term in the equation itself. I have
obtained solutions in the past using a shooting procedure: guess a
value for the 2nd, use RK4 to march solution from one boundary to the
other, then iterate until value for 2nd derivative produces correct
boundary value at the far end.
I have no hope of an analytic solution. I would like to know if
Mathematic 2.2 or 3.0 has numerical tools that can handle this
problem. Thanks ... I appreciate the help.
