Caramana Kernel

[Jeffrey Oldham]

	The Caramana hydrodynamics kernel is now available in the Pooma
CVS tree at examples/NewField/Caramana/.

	The initial conditions are a constant pressure and arbitrarily
zero velocities.  The boundary conditions are zero normal components
along the coordinates axes and zero velocity for the origin.

	As the simulation runs, the cells furthest from the origin
should spread away from the origin.  As these spread, the other cells
start spreading.  To make this visible, modify the code to increase
the time step and increase the number of iterations.

	I do not know of analytical solutions to double check the
solution.  Don or Jean, do you know?

Thanks,
Jeffrey D. Oldham
