Enhancements to the eXtensible Data Model and Format (XDMF)

reportActive / Technical Report | Accession Number: ADP023792 | Open PDF

Abstract:

The eXtensible Data Model and Format XDMF is an active common data hub used to pass metadata and value between application modules in a standard fashion. XDMF views data as consisting of two basic types Light data and Heavy data. Light data is both meta data and small amounts of values. Heavy data typically consists of large arrays of values. Support for XDMF is included in the widely used visualization package ParaView, computational codes like ALE3D from Lawrence Livermore National Laboratorv LLNL and the SIERRA computational framework from Sandia National Laboratory SNL. A major effort is now under way to enhance xDMF to more directly support concepts like Adaptive Mesh Refinement AMR, mixed topologies, higher order elements and parallel datasets. Discussed here are the motivations for the enhancements and the benefits of the new version.
