Hello everyone,

I met a strange error when using smooth_mesh. It seems that I could not create the object Domain, however, I have verified that the voxel-mesh was quite nice. 

  coordssmooth = smooth_mesh(m, 4, 0.6307, -0.6347, None, True, False)
  File "/usr/local/lib/python2.7/dist-packages/sfepy/mesh/mesh_tools.py", line 505, in smooth_mesh
    domain = Domain('mesh', mesh)
  File "/usr/local/lib/python2.7/dist-packages/sfepy/fem/domain.py", line 223, in __init__
  File "/usr/local/lib/python2.7/dist-packages/sfepy/fem/domain.py", line 375, in setup_facets
  File "/usr/local/lib/python2.7/dist-packages/sfepy/fem/facets.py", line 281, in setup_unique
    self.uid[0], self.uid[1:] = 0, ii[:-1]
IndexError: index out of bounds
