Dear all,
I'm trying to solve the *time-independent* 2D sine-Gordon equation (u_{xx} +
u_{yy} - sin(u) = 0) using deal.II. Is anybody aware of any implementation
existing, or perhaps any other elliptic semilinear PDE, or even a Newton method
implementation for elliptic non-linear PDEs?
Please note that I'm aware of tutorial 25 which solves the sine-Gordon equation,
however, it solves the *time-dependent* one and I can't see how I can make use
of it.
Thanks in advance.
