Hi Kevin,
Thanks again for your valuables efforts!
Yes, what you say with words is exactly what I would translate in pseudo-code!
Do you think that it would possible? Perhaps Peter could also give his opinion.
We keep us informed.
Thanks again!
Roland

Re: Steady state convergence tolerance
Hi, It is a bit difficult to really understand how all the convergence tolerances interact during the solve only in sentences, Kevin. I saw the ElmerSolverManual's 1.2 part (Handling interactions of multiple physical phenomena) which shows the pseudo-code of the handling of a multiphysics equation s...

Re: Steady state convergence tolerance
Hi,
Thanks a lot Kevin for your detailed explanation which I will read and come again to you if I have some more points to clear.

Re: Steady state convergence tolerance
Hi, Having no answer about my former post I will try to ask the things on a more simple way: In a non linear multiphysics coupled model I would like to better understand how the nonlinear convergence tolerance and the steady_state convergence tolerance interact when the solver works. Can this be exp...

Re: Steady state convergence tolerance
...Sorry, my former post has been interrupted. I continue it here after: I am still trying to better understand how all the linear, nonlinear, steady_state convergence tolerances interact in a time dependant nonlinear multiphysics coupled problem. In the Elmer solver manual a pseudo-code describes t...

Re: Steady state convergence tolerance
Hi Peter, After thinking this "Steady state convergence tolerance" matter a bit more and after reading one of your former post explaining the 3 convergence nested levels (liner, nonlinear and loosely coupled equations system) I think I understand now what is the "Steady state": w...

Re: Steady state convergence tolerance
Hi Peter, Thanks for your answer. But I still don't feel exactly what this convergence criterion (which I understand for non-linear and linear iterations when using a solver) is for " steady state ". What do you mean exactly by "Steady state" ? What confuses me is that you refer ...

Re: Steady state convergence tolerance
Hi, Thanks Kevin for your reply. But how could this stopping criterion be applied to the equation? What is the error expression defined for this equation which gathers all the concerned solvers? Is there something like a flowchart which could describe this kind of convergence test? Thanks in advance...

Steady state convergence tolerance
Hi, Concerning the linear/non linear convergence tolerance of a solver is roughly ok for me about the understanding of how it works. But I don't understand how the "Steady state convergence tolerance" works when using a solver. How is this convergence tolerance taken into account? Could so...

Re: Temperature plotted in non activated body
Hi, Just for information about using the Theeshold filter here attached is a plot of the time dependant "Crystal Growth in Cold Crucible" model which shows (at t=200s): - temperature field (colour) in the liquid/solid Silcon body (the phase change interface is the thick white line) -magnet...
