JAX-FEM 0.0.12 (Jun 2026)#

  • Major updates

    • Unified solver() for Newton, arc-length (displacement & force control), and dynamic relaxation; legacy flat solver_options still work for Newton.

    • Newton: per-iteration residual/timing logs; PETSc global-matrix cache.

    • New/refactored applications: third medium contact, updated Lagrangian, differentiable mesh; updated arc-length and dynamic-relaxation examples.

    • Documentation: inverse-problem tutorials, notebook reorganization, box_mesh_gmsh API fixes in examples.

  • Breaking changes (from 0.0.11)

    • gauss_order → quadrature_order (optional quadrature_rule added).

    • umfpack_solver → spsolve_solver.

    • Arc-length / dynamic relaxation: use solver({'arc_length': ...}) and solver({'dynamic_relax': ...}).

JAX-FEM 0.0.11 (Aug 31, 2025)#

  • Major updates

    • Fixed a bug in MMA solver.

JAX-FEM 0.0.10 (Aug 08, 2025)#

  • Major updates

    • Use jax.tree_util.tree_map() to replace the deprecated jax.tree_map(). See JAX updates jax 0.4.26 (April 3, 2024).

    • Support AMGX linear solver for better performance on GPU.

JAX-FEM 0.0.9 (May 05, 2025)#

  • Major updates

    • Support customized linear solvers

JAX-FEM 0.0.8 (Oct 30, 2024)#

  • Major updates

    • Implement the arc-length solver

JAX-FEM 0.0.7 (Aug 18, 2024)#

  • Major updates

    • Update jax_fem.solver to include scipy solver
