merc2d_s0p5 Local hybrid simulation of shear layers at the dusk and dawn flanks of Mercury's magnetotail, for a sodium ion density equal to half the magnetospheric proton density. Available products: B, Bx, By, Bz, nmsp, nNa, nswp |
||
CoordinatesThe 2D simulation plane is in Mercury's equatorial plane, with the local magnetic field in the z-direction, the solar wind velocity in the y-direction, and velocity shear (gradient) in the x-direction. The centre (in x) is dominated by the solar wind population, and the outer edges are dominated by the magnetospheric populations. The simulation is periodic in both x and y. |
Initial conditionsMagnetic field B = (0,0,1) in simulation units. Magnetospheric proton, solar wind proton, and sodium ion number densities = (1,4,0.5) normalised to the magnetospheric proton number density. Thermal velocities (0.4,1.2,0.2) in units of the magnetospheric proton Alfven speed. Solar wind velocity = 0.8v_A. |
ParametersGrid size: Nx=256, Ny=252; Time step: dt=0.02 in units of inversed proton gyrofrequency. Cell size: dx=dy=0.5 in units of proton inertial length. |
