<p>Hi all,</p>
<p>I have 2 questions which I hope are easy to answer; I am a bit
stuck when trying to change the material in the laserslab example.
<br>
</p>
<ul>
<li>I am trying to use the polystyrene ionmix4 file which is in
the same format as the aluminium one however it returns an error
that it can't be found. Any ideas why this is so?<br></li></ul></div></blockquote><div>Where are you running the executable? Perhaps you have not moved that particular file to the directory where you are running the <font face="monospace">./flash4</font> executable. If you are running the executable in the <i>object</i> directory where you have configured and made it, then the default Simulation module for the <i>LaserSlab</i> problem will have not moved that particular file there. You can change this by editing the <i>Config</i> file. For instance, I can see that in my version of the <i>LaserSlab</i> problem, it will only copy these files to the object directory:<br>

However, if you want to do standardized extractions of the species you're using as materials in FLASH, as well as acquire information such as the electron and ion densities, make sure you're using 3T and take a gander at page 539/section 34.7 of the user manual. </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><ul>

<p>I have attached my .par file. I would much appreciate some help!
I am using FLASH.4.6.2 and setup command was <br>
</p>
<p>./setup -auto LaserSlab -2d +cylindrical -nxb=16 -nyb=16
+hdf5typeio species=cham,targ +mtmmmt +laser +uhd3t +mgd
mgd_meshgroups=6 -parfile=VulcanTest2.par<br>

<p>Thanks in advance,</p>
