One of the best places to see how BCs have been solved is www.wilmott.com, especially Numerical Methods.
The situation is very, very extensive.

Dear Sun,
I am not part of Quantlib team, however I would say that none of your guess are correct: transparent Boundary Conditions should be used. However, if the grid is large enough, Neumann or Dirichlet are a correct alternative for a classical FD approach.
Note that there exists also FD approaches for European or American pay off that do not use any boundary conditions.

HI,
In FDEuropeanEngine module, if I'm right, the boundary conditions are
set up in FDVanillaEngine::initializeBoundaryConditions. They are
NeumannBC, but as I know from the BS PDE,
we only know the option value on the upper and lower boundaries,
shouldn't they be DirichletBC ?
please help to advise.
thanks,
sun
