<p style="margin: 0px 5px 0px 0px;"><span style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:#000000;text-decoration:none"><br /></span>I am going to simulate a problem with a laser heated foil (say aluminum) with expanding plasma from its back</p>
<p style="margin: 0px 5px 0px 0px;">towards another target (say a gas jet). Both targets are separated by low-density gas (e.g. helium, like in the Laserslab</p>
<p style="margin: 0px 5px 0px 0px;">example). The laser is coming almost normally to the front side of the aluminum foil (or another metal).</p>
<p style="margin: 0px 5px 0px 0px;">So far, I was preparing the atomic data (EOS, opacities). Now, I would like to get some primary help in setting up the</p>
<p style="margin: 0px 5px 0px 0px;">geometric parameters of the simulation. The laser part I can take from the mentioned example case.</p>
<p style="margin: 0px 5px 0px 0px;">How should I define correctly the case of more than two species and their positions?</p>
<p style="margin: 0px 5px 0px 0px;">Probably, it makes sense to start in 1D. Later, the 2D geometry and the MHD option can be applied.</p>
