✦ Synopsis

The integrated space-time finite volume method for predicting time-dependent fluid flow problems is developed. By enforcing discrete conservation over spacetime control volumes which fill the space-time domain, this method satisfies global conservation in space-time while automatically satisfying the Leibnitz Rule and geometrical conservation law. The method is validated using a variety of two-dimensional problems featuring both prescribed and free boundary motion. Advances in other aspects of cell-centered finite volume discretization-most notably in the modelling of diffusion terms and free surface flows-are also described.

In the space-time conservation element and solution element (CE /SE) method, the independent marching variables used comprise not only the mesh values of the physical dependent variables but also, in contrast to a typical numerical method, the mesh values of the spatial derivatives of these physical
