Hello, I need to get the norm of the solution (local variable norm_delta) of the current newton step after each solve in NewtonSolver::solve(). What would be the best way to extend NewtonSolver to get this value in my application code? I was thinking of a callbackapproach, where I could add a functionpointer to NewtonSolver and the solve routine calls this function with the wanted value. Would this be a solution which could make it into the official libmesh? Does anyone has a better solution for this (beside parsing the output). Robert
