abstract = {<p style="text-align: justify;">This work is devoted to the numerical approximation of three-temperature
multi-material hydrodynamics. Such systems are subject to stiff phenomena which require specific care during the discretization. In particular, the so-called discrete equation method is here applied to the radiation transport, in the optically-thick limit. This
strategy is shown to be accurate in the presence of in-cell interfaces while being simpler
than standard interface reconstruction techniques. It is then incorporated into a three-temperature multi-material scheme whose implicit temporal discretization is based on
convex combinations. Stiff test cases eventually establish the scheme’s robustness.</p>},
