Hi all,

Please tell me the class of this equation, and if possible how to solve this kind of equations:

[itex]\Delta[/itex]u([itex]\vec{r}[/itex])=F(u([itex]\vec{r}[/itex]),[itex]\vec{r}[/itex])

Thanks in advance.

3D 2nd order non-linear - no 1st order term.
IIRC: There are no general approaches for solving this type of equation.
The trouble is that the RHS function can be ANYTHING.
