◆ evaluate()

double chrono::vehicle::LinearDamperForce::evaluate ( double  time,
double  rest_length,
double  length,
double  vel,
const ChLinkTSDA link 
)
overridevirtual

Calculate and return the general spring-damper force at the specified configuration.

If the link has internal ODE states, the current states can be accessed with link->GetStates().

Parameters
