DESCR (862B)
1 The purpose of the MED module is to provide a standard for storing and 2 recovering computer data associated to numerical meshes and fields, and to 3 facilitate the exchange between codes and solvers. 4 5 The persistent data storage is based upon HDF format (like CGNS, a standard 6 developed by Boeing and NASA in the area of Computational Fluid Dynamic). 7 8 MED also provides structures to hold data on meshes and fields. These 9 structures are exchanged between solvers, hide the communication level (CORBA 10 or MPI), and offer persistence (read/write in .med files). 11 12 The main benefit of a common exchange format is reduced complexity of code 13 coupling. It also allows sharing such high level functionalities as computation 14 of nodal connectivity of sub-elements (faces and edges), arithmetic operations 15 on fields, entity location functionalities, and interpolation toolkit.
