We apply continuum approach to follow the dynamics of irradiated complex samples. First we discuss its advantages and limitations when compared to other modelling methods. We then apply this approach to describe data on irradiated clusters and laser-created plasmas that were recorded at the free-electron-laser (FEL) FLASH facility at DESY Hamburg. We show a good agreement between experimental results and our theoretical estimations. Finally we give an outlook on applying the continuum approach to describe ultrafast transitions within FEL-excited solids.
