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) (`SID2` ≠ `SID1`)
`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)
