The sequence shows the evolution of dynamic structures resembling tornadoes in the solar atmosphere. The blue and green color scheme shows the vorticity in the solar atmosphere in the regions where solar tornadoes appear. The plane shows the magnetic field strength about 1Mm below the solar surface where $\tau=1$. One can clearly see that the vorticities are closely related to the subsurface magnetic field.

The sequence shows the evolution of dynamic structures resembling tornadoes in the solar atmosphere. The blue and green color scheme shows the vorticity in the solar atmosphere in the regions where solar tornadoes appear. The reddish contour shows the dynamic evolution of the $\beta=1$ layer, the gray contour displays the $\tau=1$ layer.

The sequence shows an impacting body on a ductile target made of Al6061-T1. The impacting body is assumed to be ideally hard. The impact velocity is $45 \mathrm{m/s}$ and is tilted $51^°$ from the horizontal axis. The spacing of the SPH particles is $50\mu \mathrm{m}$.
The depth of the crater is compared to the experimental results by Takaffoli & Papini (2012).
