How to define a boundary condition complexly given at two points?

Please login with a confirmed email address before reporting spam

Hi, everyone

I am solving a 1D PDE problem with general form. One of the boundary conditions is very special and is given at two points.

The PDE problem has 2 variables (y1 and y2) and 2 boundarys (x=0 and x=d).
This BC is: y1(0)=y1(d)*y2(0)*exp(y1(0)+y2(d)).

So special the BC is! how to handle it?

Thank you!

youf.
