<span style="font-family:SimSun;" class="">Recently, I do the simulation of the process which 30fs laser interact with 5 microns thickness aluminium foil, but it seems that the magnetic field generated by Biermann battery effect is badly consistent with the result of the experimental and simulation published. And I am not sure weather Flash4.6.2 can simulation the fs laser interact with matter.</span>

<span style="font-family:SimSun;" class="">According to the article:10.1103/PhysRevLett.110.015003 ,the magnetic field can reach 10^3 T at 1ps , but the simulation result is only about 10^3 Gauss.</span>
