HDF5File

class dolfin.cpp.io.HDF5File(comm, filename, file_mode)

Bases: dolfin.cpp.common.Variable

Constructor. file_mode should “a” (append), “w” (write) or “r” (read).

attributes()

close()

Close file

flush()

Flush buffered I/O to disk

has_dataset()

Check if dataset exists in HDF5 file

read()

Overloaded versions

• read(x, dataset_name, use_partition_from_file)

  Read vector from file and optionally re-use any partitioning that is available in the file

• read(u, name)

  Read Function from file and distribute data according to the Mesh and dofmap associated with the Function. If the ‘name’ refers to a HDF5 group, then it is assumed that the Function data is stored in the datasets within that group. If the ‘name’ refers to a HDF5 dataset within a group, then it is assumed that it is a Vector, and the Function will be filled from that Vector

• read(mesh, name, use_partition_from_file)

  Read Mesh from file and optionally re-use any partition data in the file

• read(meshfunction, name)

  Read MeshFunction from file

• read(meshfunction, name)

  Read MeshFunction from file

• read(meshfunction, name)

  Read MeshFunction from file

• read(meshfunction, name)

  Read MeshFunction from file

• read(mesh_values, name)

  Read MeshValueCollection from file

• read(mesh_values, name)

• read(mesh_values, name)

  Read MeshValueCollection from file

thisown None
