chrono::fea::ChLoaderBeamWrenchDistributed Class Reference

Description

Distributed constant wrench.

Loader for a constant wrench (force+torque) distributed on a beam. An distributed wrench on the beam contains a "force per unit length" and a "torque per unit length"

Member Function Documentation

ComputeF()

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

inlinevirtual

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.

Parameters

U	parametric coordinate in line
F	result vector, size = field dim of loadable
state_x	if != 0, update state (pos. part) to this, then evaluate F
state_w	if != 0, update state (speed part) to this, then evaluate F

Implements chrono::ChLoaderU.
