Output vtk file with field_data

[tianxia3]

field_data can be read from most mesh format. But when writing to vtk, the field_data is apparently missing, leaving only the points, cells, point_data and cell_data.

Is it possible to output the field_data as well? As stated in: https://vtk.org/wp-content/uploads/2015/04/file-formats.pdf

Field data is a general format without topological and geometric structure, and without a particular dimensionality.
Typically field data is associated with the points or cells of a dataset. However, if the FIELD type is specified as the
dataset type (see Figure 1), then a general VTK data object is defined.
