Self-generated magnetic fields modelling within high-order Lagrangian magneto-hydrodynamics
Original language description
The mechanism of magnetic field self-generation due to crossed gradients of density and temperature is known for a long time from the astrophysical context, but it finds its importance even within modelling of laser–target interaction and inertial confinement fusion in particular. Therefore, it is highly desirable to incorporate this phenomenon to the magneto-hydrodynamic description commonly used for magnetized dense plasmas. Specifically, Lagrangian framework modelling the physics of interaction in the moving fluid frame is considered. However, the classical approaches suffer from the detrimental selfamplification process known as the Biermann catastrophe. We propose a stable method for modelling of the Biermann battery effect within the two-temperature high-order curvilinear finite element hydrodynamics, which also maintain the magnetic field divergence-free. Construction of the method is reviewed and verified on a physically relevant simulation.
