%description
Smith is a 3D implicit nonlinear thermal-structural simulation code for
investigating abstraction strategies and implicit finite-element algorithm
development on emerging architectures. It is built on the LLNL RADIUSS stack
(Axom, MFEM, Tribol). This is a pre-alpha release.

%changelog
* Thu Oct 08 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-0.4.20260618git292e743b
- Rebuild against mfem 4.10-1.1 (soname libmfem.so.4.10.0)
- Patch0: define MFEM_UNREACHABLE when mfem does not (mfem 4.10 dropped it).

* Thu Oct 08 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-0.3.20260618git292e743b
- Build against compat-lua (Lua 5.1) on Fedora 45+, to match axom 0.15.0-3 (sol2 rejects Lua 5.5).

* Wed Oct 07 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-0.2.20260618git292e743b
- Rebuild against the RADIUSS 2026.09 refresh (camp 2026.07.2, RAJA 2026.07.1, conduit 0.9.9, axom 0.15.0-2, tribol 0.3)

* Fri Jul 03 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-0.1.20260618git292e743b
- Drop upstream examples and the partitioner tool: they fail to build with GCC 15
  (-Wtemplate-body) because solid_mechanics_contact.hpp uses StrumpackSolver
  outside its #ifdef guard. Libraries and headers are unaffected.
- Add STRUMPACK + superlu_dist MPI BuildRequires (mfem contact solver links them)
- Initial package (pre-alpha snapshot; MPI-only; bundles gretl + ContinuationSolvers)
