Description
Interface for objects that can be subject to loads (forces) Forces can be distributed on UV surfaces, or lines, etc.,so look also the more detailed children classes.

◆ LoadableStateIncrement()
|
pure virtual |
Increment all DOFs using a delta.
Default is sum, but may override if ndof_x is different than ndof_w, for example with rotation quaternions and angular w vel. This could be invoked, for example, by the BDF differentiation that computes the jacobians.
