chrono::fea::ChLoadBeamWrench Class Reference
Description
Atomic wrench (ready to use load) Load for a wrench (force+torque) at a specific position of a beam.
The ChLoaderBeamWrench is a 'container' for ChLoadBeamWrench. 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:
