Definitions

Field Contents SI Unit Example
CID Contact identification number.

No default (Integer > 0)

SID1 Set identification number for a set of elements.

No default (Integer > 0)

SID2 Set identification number for a set of elements.

No default (Integer > 0) (SID2SID1)

CNFTYPE Contact normal force type.

Default = POISSON

PENAL Penalty factor.

Default = 1.0 (Real > 0.0)

COR Coefficient of restitution.

Default = 1.0 (0.0 ≤ Real ≤ 1.0)

MUSTAT Coefficient of static friction.

Default = 0.0 (Real ≥ 0.0)

MUDYN Coefficient of dynamic friction.

Default = 0.0 (Real ≥ 0.0)

CFFTYPE Contact friction force type.
COUL (Default)
Activates the Coulomb Model of Friction, where the coefficient of friction used depends on the specified Stiction Transition Velocity (STVEL) and Friction Transition Velocity (FTVEL).
DYNA
Activates the Dynamic Friction model, where only the Dynamic Friction is active.
NONE
STVEL Stiction transition velocity. Defines the slip velocity at which the static coefficient of friction MUSTAT is applied.

Default = 0.0 (Real ≥ 0.0)

FTVEL Friction transition velocity. Defines the slip velocity at which the dynamic coefficient of friction MUDYN is applied.

Default = 0.0 (Real ≥ 0.0)
