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()
|
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
