# Upstream's commit of 2026-02-24, the one built for FEBio 4.12 (tagged the next

Version:        1.0.0^%{snapdate}git%{shortcommit}
Release:        2%{?dist}
Summary:        Reaction-diffusion plugin for the FEBio finite element solver

# The repository has no licence file and no licence notice in any source file.
# Packaged as MIT, the licence of FEBio itself, on Morgan's decision until upstream
# answers (asked in docs/upstream/febio-questions.md). Revisit before any wider use.

# 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.

%description
FEBioChem adds the reaction-diffusion and reaction-diffusion-convection
modules to FEBio: diffusing solutes and solid-bound species coupled by
mass-action, Michaelis-Menten, logistic-growth and negative-order reactions.

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