◆ SaveInternalState()
|
inlinevirtual |
Save the internal state of this timestepper, for checkpointing.
The internal state is any data carried from step to step that is not stored in the integrable object (the state, accelerations, and Lagrange multipliers are). See the developer manual on the physics item lifecycle.
Reimplemented in chrono::ChTimestepperImplicit.
The documentation for this class was generated from the following files:
- /builds/uwsbel/chrono/src/chrono/timestepper/ChTimestepper.h
