Mesh distribution for 1D problem

Netgen
1

Hello, I have a problem with 1D mesh. The simple code below gives me an error only when I run it from mpirun. Is there any way to overcome this problem?
I use ngsolve 6.2.2305.post35.dev. Thank you in advance for your comment.

The error messages (output):

segi: 0
points: 1 3
surfels:

Traceback (most recent call last):
  File "/path/to/file/test.py", line 28, in <module>
    mesh = m.Distribute(comm)
           ^^^^^^^^^^^^^^^^^^
netgen.libngpy._meshing.NgException: no surface element found

Code:

import ngsolve
from netgen.meshing import *

def mesh1d():
    m = Mesh(dim=2)

    # Nodes
    p1 = m.Add(MeshPoint(Pnt(0, 0, 0)))
    p2 = m.Add(MeshPoint(Pnt(1, 0, 0)))
    p3 = m.Add(MeshPoint(Pnt(2, 0, 0)))

    # Element 0D
    idx_left = m.AddRegion("left", dim=0)
    idx_right = m.AddRegion("right", dim=0)

    m.Add(Element0D(p1, index=idx_left))
    m.Add(Element0D(p3, index=idx_right))

    # Element 1D
    idx = m.AddRegion("material", dim=1)
    m.Add(Element1D([p1,p3], index=idx))
    return m


comm = ngsolve.MPI_Init()
if comm.rank==0:
    m = mesh1d()
    mesh = m.Distribute(comm)
else:
    mesh = Mesh.Receive(comm)
2

Looks like this is not supported, nobody worried about parallelization of 1D meshes with Netgen, so far.
