If a solution diverges that means the iterative process that is supposed to drive the initial guess of the solution to the actual solution has failed and instead the solution has been driven further away from the actual solution.
There are many things that could cause this including inconsistent specification of physics/boundary conditions or not applying enough relaxation to stabilize the numerical method. Generally it means your problem is ill-posed in some way or the iterative method is unstable in some way.
