Question about plasma cloud expansion simulation
Hello!
Currently I'm simulate the plasma cloud expansion using my 3D hybrid PIC code. Model description and some results of my code are available at http://comphys.narod.ru/3d_cloud_v3.htm. The simulation results are reasonable in general. But some contraversal results http://comphys.narod.ru/m20d14.htm turn out in case of the Ma 10/ Especially suspicious things occur on a equatorial plane: http://comphys.narod.ru/m20d14.htm#CloudVelocityXY http://comphys.narod.ru/m20d14.htm#MF_XY where the spatial anisotropy of cloud expansion is observed Couldn't you help me to understand the reasons of such discrete anisotropy?
