A method is described to solve the time dependent incompressible flow with finite difference method on curvilinear moving grid in three dimensions. The scheme is fourth-order accurate in space and uses the momentum equations for the velocity coupled to a Poisson equation for the pressure. The fourth-order consistent scheme is applied to the convective terms in the Navier-Stokes equation. In this investigation, the flow around periodic bending flat plate is computed. As the results of this investigation, drag and lift force around deformating plate can be estimate. It is also demonstrated that fractional step method are required to advance the solution from n to n+1 instead of the rezoning method.
