Velocity field and density of a slice in the (x,z) plane in the region of hydraulic jumps for the primary (top panel) and secondary (bottom panel) in the HIDECL model. Both disks are centered on their parent stars to properly compute the gas velocity field. The scales in x and z are different in the two plots and, in addition, the star is on the right in the top plot (circumprimary disk), while it is on the left in the bottom one (circumsecondary disk).
