Suppression of spiral in centric field is investigated. The spiral is suppressed by circumrotating the system with mechanical force. It is the first time spiral is supressed and spatiotemporal chaos dispelled using this scheme. The Fitzhugh-Nagumo equation and Panfilov equation are investigated, and numerical simulation shows that the scheme is effective and robust to certain white noise.
