Development of a Finite Volume Based Structural Solver for Large Rotation of Non-Orthogonal Meshes

Finite element analysis has dominated the world of computational structural mechanics for the past half century, however, since seminal work by Demirdžic et al. [1] finite volume stress (FV) analysis has become a viable alternative. The apparently simple problem of a body undergoing large rotation is far from trivial when considered numerically. This research develops a large strain FV structural solver that accurately calculates the large rotation of solid bodies with particular attention paid to non-orthogonal meshes and mesh movement.
