You'd want it after each linear solve, or before or after each proposed step, or before or after each completed step? > I was thinking of a callback-approach, where I could add a > function-pointer 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). We've been using subclassable functors for callbacks lately, which is strictly more flexible than using global callback functions. It's sometimes more tedious to code, though, so I'll leave the decision up to you. Would you also pass norm_total and any other easy-to-grab parameters too? If we're going to add a new API to expose internals we should make it as useful as possible.
