How to gain the exact solution of the partial discrete equation...












0












$begingroup$


I made a mathematical discrete model of one dimensional flow.
Then I achieved this equation:



$u(n,m+1)=u(n-1,m)+u(n,m)(u(n+1,m)-u(n-1,m))$



Where n ,m are integer and $0leq u leq 1 $ for all n, m.



Numerical experiments implies it has traveling wave solution under moderate boundary condition.I want to know its exact solution.Please tell me.

    I heard that Burgers' equation is pretty well studied.
