Abstract
An efficient and versatile mesh method is suggested and implemented for problems involving individual overlapping mesh blocks around moving objects. The overlapped mesh blocks are combined using a stitching stripe, which considers smooth transition of the mesh element size between the blocks. Interpolation of the flow values between the mesh blocks is not needed. This is considered as a relative advantage of this method compared to the overset mesh method. Unsteady flow around an oscillating body test case is used to demonstrate applicability of this method. Other test cases include hypothetical multiple flapping airfoils in relative motion and store separation from a store bay.
