To export meshes there is one method that exports the mesh to paraview-xdmf-format: Mesh.save_mesh_xdmf().
This method belongs to the Mesh-class.
The export can be done by calling:
>>> field_list = [(q_red, {'ParaView':False, 'Name':'q_red'}),
(eps, {'ParaView':True,
'Name':'epsilon',
'AttributeType':'Tensor6',
'Center':'Node',
'NoOfComponents':6})]
>>> my_mesh.save_mesh_xdmf(filename, field_list, bmat, u, timesteps)
The filename-parameter gives the filename the xdmf-file is saved as.
The parameters u and timesteps can be passed if one wants to save the displacements of the geometry for different
timesteps. Hereby u is passed as a numpay array.
The parameter field_list can be used to store additional fields in hdf5. The parameter is a list of tuples that contain
two items. First the data-array and second a dictionary that contains metadata.
If the key Cell is set to Center then this dataset is seen as belonging to elements.
If the key ParaView is set to True the dataset is both imported to hdf5 and to paraview xdmf.
The other attributes are passed to the function create_xdmf_from_hdf5 . See documentation of xdmf and paraview for
more details.
