chrono::fea::ChLoaderBeamWrench Class Reference


Atomic wrench.

Loader for a wrench (force+torque) at a specific position of a beam. An atomic load on the beam is a wrench, i.e. force+load applied at a certain abscissa U, that is a six-dimensional load. It is not a distributed load, so inherit it from ChLoaderUatomic.

◆ ComputeF()

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

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
