222 +This example demonstrates Parameter Space Exploration (PSE) by running multiple TVB simulations in parallel for different parameter combinations. 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).
