Spatially Non-uniform Time-Step Adaptation in Unsteady Flow Problems Karthik Mani and Dimitri J. Mavriplis † Department of Mechanical Engineering, University of Wyoming, Laramie, Wyoming This paper presents a space-time finite-volume formulation for the Euler equations, which allows for the use of spatially non-uniform time-steps. Finally, aerodynamic calculations of flow over a variable-sweep wing are compared with experiment, and the effect of varying the sweep on the aeroelastic damping is studied.
