There are various mesh formats available for representing unstructured meshes, e.g.,
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
points = numpy.array([
[0.0, 0.0, 0.0],
[0.0, 1.0, 0.0],
[0.0, 0.0, 1.0],
])
cells = {
'triangle': numpy.array([
[0, 1, 2]
])
}
meshio.write(
'foo.vtk',
points,
cells,
# Optionally provide extra data on points, cells, etc.
# 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).
