// Example of a C++ adaptor for a simulation code
// where the simulation code has a fixed topology
// grid. We treat the grid as an unstructured
// grid even though in the example provided it
// would be best described as a vtkImageData.
// Also, the points are stored in an inconsistent
// manner with respect to the velocity vector.
// This is purposefully done to demonstrate
// the different approaches for getting data
// into Catalyst. Note that through configuration
// that the driver can be run without linking
// to Catalyst.
