Hi Guys,

I want to solve this equation:IMAGE 1.In my solver I write my equation in this form:Is this write?

solve
            (
                fvm::laplacian(T)-a*pow(T,4)
            );

Luckly I can solve this equation,but my problem is only a is a very small number such as 0.000000000000001 can this equation be solved.

I want to use OpenFOAM solving this simple PDE I think its not a thing.There must be something wrong in my setting.Anyone help me check it out?and how can I get the analytic solution?Thanks in advance.
