Member Function Documentation

virtual void chrono::ChLoaderUatomic::ComputeQ ( ChVectorDynamic<> *  state_x,
ChVectorDynamic<> *  state_w 
)
overridevirtual

Computes Q = N'*F.

Parameters
state_xif != 0, update state (pos. part) to this, then evaluate Q
state_wif != 0, update state (speed part) to this, then evaluate Q
