Abstract

Allen–Cahn (Ginzburg–Landau) dynamics for scalar fields with heat conduction is treated in rigid bodies using a nonequilibrium thermodynamic framework with weakly nonlocal internal variables . The entropy production and entropy flux is calculated with the classical method of irreversible thermodynamics by separating full divergences.
