meshio 1.3.3

I/O for various mesh formats

There are various mesh formats available for representing unstructured meshes, e.g.,

• DOLFIN XML

• Exodus

• H5M

• MSH

• PERMAS

• VTK

• VTU

• XDMF

MeshIO can read and write all of these formats and smoothly converts between them. Simply call

meshio-convert input.msh output.vtu

with any of the supported formats.

In Python, simply call

points, cells, point_data, cell_data, field_data = \
    meshio.read(args.infile)

to read a mesh. To write, do

meshio.write(
    args.outfile,
    points,
    cells,
    point_data=point_data,
    cell_data=cell_data,
    field_data=field_data
    )

For both input and output, you can optionally specify the exact file_format (in case you would like to enforce binary over ASCII VTK, for example).
