Advection
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.
Advection B
In input deck B an Eulerian formulation with 1st order advection is used. As it travels through the bar, the plastic strain field is stretched and its maximum value decreases.
Advection C
In input deck C an Eulerian formulation with 2nd order advection is used. Distortion of the plastic strain field is now much less in comparison with 1st order advection.
Advection SFSAFSF
This is a Lagrangian msdfsdfasfdaAf 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.
