In this review, we describe the application of Boltzmann kinetic equations for modelling warm dense matter and plasma formed after irradiation of solid materials with intense femtosecond X-ray pulses. Classical Boltzmann kinetic equations are derived from the reduced N-particle Liouville equations. The first version of the Boltzmann kinetic equation solver was completed in 2006. The code was adapted to study plasma created from X-ray-irradiated materials. In order to avoid treatment of a very high number of active atomic configurations involved in the excitation and relaxation of X-ray-irradiated materials, an approach called ‘predominant excitation and relaxation path’ (PERP) was introduced. The performance of the Boltzmann code is illustrated in the examples of X-ray-heated solid carbon and gold. This article is part of the theme issue ’Dynamic and transient processes in warm dense matter’.
