Displacement control problem

Post by buddhasarah » Tue Dec 27, 2011 10:01 pm

Hello, I have a question on displacement control algorithm. According to some iteration based displacement control algorithms, they seem to be indepentent from newton raphson or newton iteration method. But in Opensees, using displacement control with newton raphson or newton method takes different calculation time. So it means using newton raphson or newton method does effect the process. Can the dear moderator explain why and how this happens?
Thank you very much in advance!
