XDMFFile

class dolfin.cpp.io.XDMFFile(comm, filename)

Bases: dolfin.cpp.io.GenericFile, dolfin.cpp.common.Variable

This class supports the output of meshes and functions in XDMF (http://www.xdmf.org) format. It creates an XML file that describes the data and points to a HDF5 file that stores the actual problem data. Output of data in parallel is supported.

XDMF is not suitable for checkpointing as it may decimate some data.
