so, with flag `--setFields-only`, you can execute the `setFields` part of `particlesDict`. Now suppose that you have a simulation case which proceeded up to 2 seconds and for any reason you want to change some field value at time 3 s and continue the simulation from 3 s. To this end, you need to change `startTime` in settings dictionary to 3, execute `particlesPhasicFlow --setFields-only`, and start the simulation.
