This command is used to construct a VPDependent friction model object.
| frictionModel VPDependent $frnTag $muSlow $muFast0 $A $deltaMu $alpha $transRate |
| $frnTag | unique friction model object tag |
| $muSlow | coefficient of friction at low velocity |
| $muFast0 | initial coefficient of friction at high velocity |
| $A | nominal contact area |
| $deltaMu | pressure parameter calibrated from experimental data |
| $alpha | pressure parameter calibrated from experimental data |
| $transRate | transition rate from low to high velocity |
