chrono::ChLoader Class Referenceabstract


Class for loads applied to a single ChLoadable object.

Loads can be forces, torques, pressures, thermal loads, etc. depending on the loaded ChLoadable object. For example if the load references a ChBody, the load is a wrench (force+torque), for a tetrahedron FE it is a force, etc. Objects of this class must be capable of computing the generalized load Q from the load F.

pure virtual
state_xif != 0, update state (pos. part) to this, then evaluate Q
state_wif != 0, update state (speed part) to this, then evaluate Q
