Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| CID | Contact identification number. No default (Integer > 0) |
|
| SID1 | Set identification number of a set of
nodes. No default (Integer > 0) |
|
| SRFID | Multibody deformable surface
(MBDSRF) identification number. No default (Integer > 0) |
|
| CNFTYPE | Contact normal force type.
No default (Character) |
|
| STIFF | Specifies the interface stiffness
coefficient, if CNFTYPE=LINEAR, Specifies the penalty parameter which is related to the stiffness RJTODO, if CNFTYPE=POISSON. Default = 0.0 (Real ≥ 0.0) |
|
| DAMP | Specifies the interface damping, if
CNFTYPE=LINEAR. Default = 0.0 (Real ≥ 0) Specifies the coefficient of restitution value for the contact, if CNFTYPE=POISSON. Default = 1.0 (0.0 ≤ Real ≤ 1.0) |
|
| RADIUS | Radius of the sphere geometry centered
at the origin of the I marker. Default = 0.0 (Real ≥ 0) |
