Abstract
A method for handling mesh movement in domains that deform due to movement of rigid bodies is proposed. Displacement of each node of the mesh, for any given motion of the rigid bodies, is obtained by interpolation from a set of deformed meshes corresponding to certain prescribed locations of the rigid bodies. The method is applicable to both structured and unstructured grids. It is quick and provides good quality meshes. It is applied to compute the vortex induced vibrations of a circular cylinder at Re=100 and 3728. The flow is three-dimensional at Re=3728. A stabilized finite element formulation, in primitive variables, is utilized to solve the governing equations. Results obtained with the proposed scheme show good agreement with earlier results.
