Smith Software Release Notes

Notes describing significant changes in each Smith release are documented in this file.

The format of this file is based on Keep a Changelog.

The Smith project release numbers follow Semantic Versioning.

[Unreleased] - Release date yyyy-mm-dd

Added

  • Added this release notes file to track changes in project
  • Added composable differentiable-numerics systems for solid mechanics, thermal mechanics, internal variables, and thermo-mechanics coupling through shared field stores.
  • Added combineSystems and SystemSolver support for monolithic and staggered coupled solves, including coupled relaxation algorithms, and fixed-sweep modes.
  • Added typed coupling and parameter-field registration APIs that interpolate each coupled physics pack with its own time-integration rule before invoking material, source, traction, and objective callbacks.
  • Added post-solve and cycle-zero auxiliary systems for stress projection, initial acceleration solves, and other derived-field updates in differentiable multiphysics time integration.
  • Added composable solid-mechanics and thermo-mechanics examples, tutorials, and regression tests covering coupled sensitivities, finite-difference checks, field parameters, and solves.
  • Added axisymmetric solid mechanics materials and loads for 2D (r, z) meshes.
  • Added host-configs for CZMatrix and RZVector machines
  • Added CI pipelines for CZMatrix machine
