%description
FEBio Studio is the integrated pre- and post-processing environment for FEBio,
the finite element solver for biomechanics and biophysics from the University of
Utah. It provides interactive model building, meshing, material assignment, job
control and result visualization for FEBio simulations.

This build links the system FEBio solver and enables MMG adaptive remeshing,
TetGen, CAD import/meshing (OpenCASCADE + NetGen), remote job execution over SSH,
the online model repository, SimpleITK image analysis, and Python scripting.
Video (mp4) export is not built (incompatible with the system ffmpeg version).

# CAD needs explicit Fedora paths (OCC 7.9 -> USE_NEW_OCC). FFMPEG off.

* Sat Jun 21 2026 Morgan Hough <morgan.hough@gmail.com> - 3.1-1
- Initial package: FEBio Studio 3.1, the Qt6 GUI pre/post-processor for FEBio.
  Links the system FEBio SDK (febio-devel) and enables MMG, TetGen, CAD
  (OpenCASCADE+NetGen), SSH, model repository, SimpleITK and Python scripting.
  FFMPEG video export omitted (system ffmpeg 8 dropped avcodec_close). Static
  module libs are linked into the binary; static libstdc++/libgcc removed for
  Fedora policy.
