<div>Dear all,</div><div style="text-align: start;">I want to display the self-generated magnetic field in the laser slab example, so I set plot_var_7=magx, <font color="#000000" face="-webkit-standard" size="3"><span style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.301961); -webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);">plot_var_8=magy , </span></font><span style="text-align: justify; -webkit-tap-highlight-color: rgba(26, 26, 26, 0.301961); -webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);"><font color="#000000" face="-webkit-standard" size="3">plot_var_9=magz in flash.par . But this doesn't work, and I didn't find much information in the manual for this problem. I find such usage in the magnetoHD/torus example, anyone can give me some hints? Do I need to add the magnetic field generation mechanism such as the bierman battery effect in the source term? Thanks very much.</font></span></div><div><br></div><div class="NETEASEMAILMASTERLOCALSIGNATURE"><div id="imail_signature">best wishes
