Is there a module to compute the volume of a 3D Structured Grid? We'd like to compute the volume of a model domain with a time-varying free surface location. I suppose I could go through and split each hexahedron up into pyramids, but that'll be non-trivial.

The 3D Tetrahedral Grid has a "Volumes of Tetrahedra" output, so I guess I could dump my 3D structured grid to a triangular mesh and elevations, then create a DTPrismGrid3D from it. Is that the best way? Either way, masks will be tricky to deal with.
