chrono::fea::ChLoadBeamWrenchDistributed Class Reference
Description
Distributed constant 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:

| virtual void | InjectKRMmatrices (ChSystemDescriptor &mdescriptor) |
| Tell to a system descriptor that there are item(s) of type ChKblock in this object (for further passing it to a solver) Basically does nothing, but inherited classes must specialize this. More... | |
