224 +The workflow uses two nested ForEach components to iterate over coupling and conduction speed sets of values. For each (coupling, conduction_speed) pair, a simulation run is executed with the help of the RunParallelProcess component, which runs the workflow body in separate worker processes (using multiprocessing + dill).
