# 4.12-5 ships the plugin folder and the febio.xml that imports it.
BuildRequires:  febio-devel >= 4.12-5
# Built against the FEBio 4.12 SDK headers; the plugin ABI is not stable across releases.
Requires:       (febio%{?_isa} >= 4.12-5 with febio%{?_isa} < 4.13)

%description
FEBioWarp adds image-driven loads to FEBio for deformable image
registration: a hyperelastic body is warped so that a template image
matches a target image, giving a physically regularised deformation map.

FEBio loads the plugin automatically from %{febiolibdir}/plugins.
