Can we use natural boundary conditions (if suppose I can't expressed my boundary conditions explicitly i.e. in terms of essential boundary conditions) in NDSolve.

I am trying to solve a boundary value problem (PDE) where at one end the boundary condition are expressed in terms of force (here force is a function of the dependent variable).

Though I found a link NDSolve Dankwerts boundary conditions with changing discrete variable where a natural boundary condition was used in NDSolve.

I want to make sure whether it is possible or not.
