I want to perform quasi 3D simulations over an oscillating cylinder by using mapping function. However, the velocity in the span direction (w) disappears after around 20,000 time-steps. In fact, the problem becomes full-2D after some time steps! I've tested various initial conditions for w, such as awgn(1) or awgn(1)*cos(2*PI*z/LZ), etc., and different mapping types, but I could not resolve it. I would be grateful if you could help me how to resolve this issue. The xml file and a screenshot are attached.
