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 ( 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

U	parametric coordinate in line
F	Result F vector here, size must be = n.field coords.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.
