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

Release:        2%{?dist}
Summary:        Heat transfer 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.

%description
FEBioHeat adds the heat module to FEBio: transient heat conduction with
isotropic Fourier materials, heat flux, convective and gap heat flux
boundary conditions, heat sources and initial temperatures.

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