Hydrodynamic simulations of laser/plasma interactions via ALE methods
Original language description
Hydrodynamic simulations of laser-produced plasmas represent a useful tool allowing them to investigate processes during laser-plasma interaction, which are often impossible to observe directly during the experiments. They allow not only interpretation of experimental results, but are also often used for designing the experimental setup or detailed analysis of particular processes during the experiment. In this paper, we describe the application of the Arbitrary Lagrangian-Eulerian (ALE) numerical methods, benefiting from the computational mesh moving with the fluid in a Lagrangian manner, while enforcing its geometric quality by a regular mesh smoothing mechanism. The basic ALE algorithm is enhanced by additional physical models (realistic EOS, laser absorption mechanism, heat conductivity model, cylindrical geometry, two-temperature model, phase transition model, magnetic field model, . . .), allowing to perform realistic simulations of laser/target interactions. The performance of the code is demonstrated on selected realistic numerical tests.
