I want to solve a nonlinear partial differential equation in two dimensions. I want to have fixed boundary values (inhomogeneous boundary values) and I use the multigrid algorithm for nonlinear problems (numerical recipes in C).
I have done several things to get rid of the zero boundary values in the solution, but it doesn't work. I always get zero's at the border. How can I solve this??????
Which functions do I have to adapt in order to get nonzero boundary values?????
