Figure 6:
Centerline displacement response of the 2-DOF elastically mounted rigid cylinder (Sec. 4.1.2) under grid refinement. There is excellent agreement between the ILE result on the finest grid and the results of Blackburn and Karniadakis [114] using a high order spectral element method. Simulation parameters include U* = 5, m* = 4/π, Re = 200, and ζ = 0.01.
