SI Unit Example

Istf

Interface stiffness definition flag

(Integer)

= 0: default, set to 1000

= 2, 3, 4, 5 and 6: Stfac is a stiffness scale factor and the interface stiffness is computed from both master and slave characteristics

= 1000: Stfac is a stiffness scale factor and interface stiffness is computed based only on the master side characteristics

Igap0

Gap modification flag for slave shell nodes on the free edges

(Integer)

= 0: default, set to 1000

= 1: set gap to zero for the slave shell nodes

= 1000: no change

Ipen0

Initial penetration detection flag

(Integer)

= 0: default, set to 1000

= 1: including self-impact in each part

= 1000: excluding self-impact in each part

Inacti

Initial penetration flag

(Integer)

= 0: default, set to 1000

= -1: all initial penetrations are taken into account

= 5: the master segment is shifted by the initial penetration value P0 if , then , where P0 is the initial penetration

= 1000: only tiny initial penetrations (1.0e-08) will be taken into account
