Advection A
This is a Lagrangian model of a bar that is plastically deformed at one end. To generate plastic deformation *INITIAL_STRESS_SOLID command is used. Input deck A is just a preparation for decks B and C, with which you can study how well the advection schemes preserve the shapes of the history variable fields. Download is available in the download section of this document.
