The Converger component has four configuration tabs.
Define the values for the epsilons in case of absolute and relative convergence. You can also define the number of iterations (k) which should be considered. In case of k > 1 not only the current and previous values but the minimum and maximum from the set of current plus previous k values are considered. So k = 1 means only current and previous values are considered, k = 2 current and two previous, etc. You can also limit the number of convergence checks.
Create an input for each value to consider. An output with the same name and an output with the suffix '_converged' are created automatically. In the "Add" dialog you can also decide whether to define a start value. In case if not, an additional input is created with the suffix '_start'.
