This improved unstructured dynamic mesh method, coupled with ALE Euler solver, is then applied to simulate unsteady transonic flow about harmonious oscillation of rigid wing and bend-torsion oscillation of high-aspect ratio sweepback wing of High-Altitude-Long-Endurance Unmanned Aerial Vehicles; computational results are in good agreement with those of other literatures and experiments
Introduction
Simulation complex unsteady flows with moving boundaries, such as free-surfaces, multi-body separation, aeroelastics, forced oscillation and coupling structure-fluid, is a crux in CFD.

The present article discusses the analysis of the results of simulation of NMI flowing out from the liquid steel volume in the mould zone of the steel continuous casting machine (CCM).
For computer simulation, the Computational Fluid Dynamics technique and the FLUENT®, a control volume method-based program, were used.
Boundary conditions and numerical computation procedure Computations and numerical simulations were carried out for two moulds of a cross-section of 160x160 mm and 280x280 mm, respectively.
