chrono::fea::ChLoaderBeamWrench Class Reference

Description

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 ( const double  U,
ChVectorDynamic<> &  F,
ChVectorDynamic<> *  state_x,
ChVectorDynamic<> *  state_w 
)
inlinevirtual

Children classes must provide this function that evaluates F = F(u) This will be evaluated during ComputeQ() to perform integration over the domain.

Parameters
Uparametric coordinate in line
FResult F vector here, size must be = n.field coords.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
