Hey all,

I'm trying to solve an equation of the form del^2(u) = f(u) for a non-polynomial function f. I really can't see how to do this with the gui, which seems to only be able to solve very basic equations. I have been told that it is possible to export the scripts and define the equation manually, but really have not managed to find any examples of that being done. 

I would appreciate links to documentation that explain this very much!  

Cheers 
x
