How to write vector to pointdata?

[Grayson3455]

Hi,
Is there a possible way to write vector data using write_points_cells?

For example, d is the 3D displacement field. I can write each scalar component to a .vtk file as:
meshio.write_points_cells('xxx.vtk', points, cells, {'d-x':d[0::3],'d-y':d[1::3],'d-z':d[2::3]})

But I am not be able to find a proper way to put d there. Any suggestions?

Thanks!
Best,
