+developed by Boeing and NASA in the area of Computational Fluid Dynamic).
+
+MED also provides structures to hold data on meshes and fields.  These
+structures are exchanged between solvers, hide the communication level (CORBA
+or MPI), and offer persistence (read/write in .med files).
+
+The main benefit of a common exchange format is reduced complexity of code
+coupling.  It also allows sharing such high level functionalities as
+computation of nodal connectivity of sub-elements (faces and edges),
+arithmetic operations on fields, entity location functionalities, and

+protocol, are automatically compatible with either the free spacenavd driver
+or the official 3dxserv, as if they were using the magellan SDK.
+
+Also, libspnav provides a magellan API wrapper on top of the new API.  So, any

+without any changes.  And programmers that are familliar with the magellan API
+can continue using it with a free library without the restrictions of the
