◆ ComputeF()

virtual void chrono::ChLoaderU::ComputeF ( double  U,
ChVectorDynamic<> &  F,
ChVectorDynamic<> *  state_x,
ChVectorDynamic<> *  state_w 
pure virtual

Evaluate F = F(u) for this line load.

The vector F is set to zero on entry. The function provided by derived classes is called by ComputeQ to perform integration over the domain.

Uparametric coordinate in line
Fresult vector, size = field dim of loadable
state_xif != 0, update state (pos. part) to this, then evaluate F
state_wif != 0, update state (speed part) to this, then evaluate F

Implemented in chrono::fea::ChLoaderBeamWrenchDistributed, and chrono::fea::ChLoaderBeamWrench.
