The study of numerical methods for the computation of gas micro flows in domains with moving obstacles is motivated by the modelling of micro-electromechanical system (MEMS), especially vibrating devices. In this framework, the flow is assumed to be well described by the BGK equation. We proposed a new numerical method for the simulation of deterministic rarefied flows with moving obstacles based on a moving mesh approach.
