Hydrodynamic modeling of self-generated magnetic fields by ALE methods

Popis výsledku v původním jazyce

Arbitrary Lagrangian-Eulerian (ALE) methods belong to the most popular approaches for hydrodynamic simulations of laser/target interactions. They benefit from improved accuracy of the simulation due to the Lagrangian motion of the computational mesh, as well as robustness resulting from a regular mesh optimization followed by conservative interpolation (remap) of all quantities between the meshes. In recent years, we were interested in modeling of spontaneous magnetic field (SMF) generation resulting from crossed gradients of electron temperature and density, known as the Biermann battery effect. Such models have been implemented in our developed 2D cylindrical Prague ALE (PALE) code, containing also all necessary physical models (EOS, laser absorption, thermal conductivity, etc.). Here, we present performance of the second-order accurate extension of the SMF generation model in the ALE framework on selected realistic tests.
