<p style="margin: 0px;"> </p>
<p style="margin: 0px;">when I'm restarting a 3D Cartesian MHD simulation (laser-induced plasma in a solenoidal magnetic field) after an initial </p>
<p style="margin: 0px;">run with Bx=0. (plasma flows in the y-direction), the new parameter definition, e.g., Bx=1e5 (10T) is not taken into account.</p>
<p style="margin: 0px;">Running the simulation with this field from t=0, all develops as expected, although the laser energy deposition is remarkably</p>
<p style="margin: 0px;">reduced because of the magnetic pressure.</p>
<p style="margin: 0px;">Perhaps, I missed something to change in the parameter file. Is there an easy solution for this problem?</p>
<p style="margin: 0px;"> </p>
<p style="margin: 0px;">Many thanks in advance</p>
