# structure liner gap-factor command

Syntax

structure liner gap-factor f

Sets the gap factor used during large-strain sliding of liner elements. During large-strain sliding, if the gap that forms between a node used by a liner element and the zone to which it is attached becomes greater than f times the zone size (where zone size is the maximum $$x$$-, $$y$$-, or $$z$$-dimension of the zone bounding box), and the normal spring is in tension, then the simulation stops and an error message is displayed. If this large gap is physically reasonable, then the simulation can be continued by either increasing f or reducing the liner tensile strength such that the normal spring breaks. By default, f equals 0.1.
