Development of ALE hydrodynamic code for laser-plasma interactions with self-generated magnetic fields

Original language description

Investigation of the laser-produced plasmas via hydrodynamic simulations belongs among popular tools allowing to design experimental setups with optimal parameters. Interpretation of complex processes which cannot be observed directly during experiments represents another field of application. Here, we present the application of the Arbitrary Lagrangian-Eulerian (ALE) framework in the context of laser-plasma simulations, which employs a computational mesh moving in a Lagrangian manner, i.e. naturally following the flow of the generated plasma. On the other hand, robustness of this approach under extreme conditions of laser/target interaction is guaranteed by a regular mesh improving mechanism followed by an accurate interpolation technique. In realistic simulations, additional physical models must be incorporated, such as accurate laser absorption, heat conductivity model, realistic equation of state, etc. In particular, we are mainly interested here in development of a magnetic field model in the context of full ALE algorithm, enabling to perform estimates of self-generated magnetic fields, when plasma density and temperature are not colinear.
