- Geometry
- Use the Longcope-Key rotating-cylinder benchmark with initial angular velocity 4000 rad/s and the open Abaqus model definitions.
- Material
- Constitutive or analytical definition: Published numerical verification plus conservation diagnostics.
- Boundary conditions
- Required solver capability: finite_rotation_explicit_dynamics. Use the loading/path control stated in the setup and preserve the complete response history.
- Measured quantity
- No independent scalar target is claimed; compare stress/history curves to the official verification and enforce angular-momentum and energy accounting.
