  abstract	= {We show how a stable and accurate hybrid procedure for
		  fluid flow can be constructed. Two separate solvers, one
		  using high order finite difference methods and another
		  using the node-centered unstructured finite volume method
		  are coupled in a truly stable way. The two flow solvers run
		  independently and receive and send information from each
		  other by using a third coupling code. Exact solutions to be
		  Euler equations are used to verify the accuracy and
		  stability of the new computational procedure. We also
		  demonstrate the capability of the new procedure in a
		  calculation of the flow in and around a model of a coral.
