from
  • BIUNIT biunit Tetrahedron
  • UNIT unit Tetrahedron
  • TETRAHEDRON General linear Tetrahedron
to
  • BIUNIT biunit Tetrahedron
  • UNIT unit Tetrahedron
  • TETRAHEDRON General linear Tetrahedron
note

If any of from or to is set to TETRAHEDRON, then xij must be provided, which represents the nodal points of a linear TETRAHEDRON. The number of rows in xij is 3 and the number of columns are 4.

info

Both from and to cannot be set to TETRAHEDRON.
