  I created a geometry and assign material for each of them.
  But after meshing end of the cone is gone/ the material change from mat 1 to mat 2 ? I check Vlist shows negative value (-2) in material of volume 3,7 (are the end of cone).
  But I assign mat 1 for those regions, why it is changed?
  
  This is how I mesh
  Meshtool>Element attributes: Global
  Mesh: volumes
  Shape: tet, free
  pick all
  
  Error says: Mid-nodes of some elements have been modified to lie on straight edges because of distortion with the original mid-nodes. This condition is sometimes eliminated by tetrahedron element improvement when enabled. Issue ESEL,,STRAIGHTENED to select such elements for listing or plotting.
  
  Thank you!
