Member Function Documentation

virtual void chrono::ChLoaderUVW::ComputeF ( const double  U,
const double  V,
const double  W,
ChVectorDynamic<> &  F,
ChVectorDynamic<> *  state_x,
ChVectorDynamic<> *  state_w 
)
pure virtual

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

Parameters
Uparametric coordinate in volume
Vparametric coordinate in volume
Wparametric coordinate in volume
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

Implemented in chrono::ChLoaderGravity, and chrono::ChLoaderXYZnode.
