poisson pde analytical solution


does there exist analytical solution or approximation to poisson equation pde in 2 dimensions


ax^4+b*x^3+c*x^2+d*x+e polinom

where BC are
where a,b,c,d,e are constants (real number)
Or if sbd knows where to look for this solution!

Re: poisson pde analytical solution

Hello jangolobow,

I donīt know what you mean with the notation D[u,x,x]+D[u,y,y], but if you donīt specify the values of x, there are infinite solutions for a, b, c, d, e. For a polynom of grade 4, 5 points must be specified to find only 1 solution. You wrote Hallo, are you dutch or belgian?
