v1.0.1

Fedoo 1.0.1

Fedoo 1.0.1 improves force recovery and nonlinear convergence checks, finite-strain Simcoon integration, composite material orientation, and viewer post-processing.

Main improvements since 1.0.0

Force recovery and nonlinear dynamics

• Recover nonlinear forces from the evaluated residual, including inertia and damping, and refresh them after vector updates and rollback.
• Preserve the completed step's force balance in linear implicit dynamics.
• Recover explicit-dynamics forces from the solved system on demand, including diagonal mass operators, without storing force snapshots.
• Include prescribed accelerations in the free equations for central difference with consistent mass.
• Evaluate the Newton force criterion even when the force reference is zero.
• Apply rigid-body forces and torques through constant Neumann conditions, keeping applied loads separate from contact and inertia in the assembled residual and preserving a nonzero current force reference in free-body dynamics.

Finite-strain Simcoon integration

• Use Simcoon's corate and direct tangent_output when supported, while retaining Fedoo's box-tangent conversion for older Simcoon versions.
• Route Simcoon step-cut requests through Fedoo's failed-increment handling.
• Make finite-strain Simcoon laws that do not convect their own material axes follow the rotating material frame.
• Use the selected corotational rate for tangent conversion in both total and updated Lagrangian formulations.

Composite material orientation

• Add degrees=False to CompositeUD for fiber angles specified in radians.
• Correct stiffness rotation for a single nonzero fiber angle, as well as arrays of Gauss-point angles.

Viewer post-processing

• Make Plot Over Line sample the currently displayed field and component after plot changes.
• Preserve Plot Over Line endpoints independently for each view when reopening the dialog or switching views.
• Let duplicated views inherit the endpoints independently.

Compatibility and migration notes

• CompositeUD continues to interpret fiber angles in degrees by default. Use degrees=False when supplying radians.
• The Simcoon adapter retains compatibility with older versions that require Fedoo's box-tangent conversion.
• Force recovery and convergence checks now use the corrected force balance, which can change reported forces and nonlinear convergence behavior in affected analyses.
