Jun 1, 2025June 2025: API cleanup for Core LinAlg interpolation to improve clarity, maintainability, and future extensibility. Removed TensorInterpolation and ScalarInterpolation namespaces; renamed WeightingFunction to ScalarInterpolationWeightingFunction; renamed InterpParams to ScalarInterpolationParams and dropped the tensor interpolation parameter. This reduces API confusion and sets a robust foundation for future performance enhancements.

Nov 1, 20242024-11 monthly summary for 4C-multiphysics/4C: Delivered major material modeling enhancements for viscoplasticity and elastoplasticity, improved anisotropy support, and reorganized the codebase to boost reliability, performance, and maintainability. Implementations included integrating KinematicQuantities and StressFactors structs, returning computed values without mutating state, refactoring the Johnson-Cook viscoplastic law, and enhancing substepping error handling. Material directories were reorganized for clearer maintenance. Anisotropy modeling now uses a descriptive anisotropy type string instead of a boolean, enabling future extensibility. The work strengthens robustness, testability, and readiness for advanced material models and future improvements.
