from

BIUNIT biunit Quadrangle
UNIT unit Quadrangle
QUADRANGLE general Quadrangle

to

BIUNIT biunit Quadrangle
UNIT unit Quadrangle
QUADRANGLE general Quadrangle

note

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

info

Both from and to cannot be set to QUADRANGLE.
