Abstract

We present an adaptive time stepping technique, based on a dual-time stepping scheme together with a RK/implicit smoother for physical time marching. This method is found to be very efficient for transient problem characterized by large variations of time scales during the physical time and hence a wide a range of required physical time steps. We discuss the method and present several examples of compressible flow problems.
