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.
