<p class="MsoNormal"><span style="font-size:11.0pt">Another option would be to set tar2 as pure carbon. Then, you would need to initialize some zones as mixed in Simulation_initBlock by setting species mass fractions TAR1_SPEC and TAR2_SPEC appropriately. You’d
still need a different EOS table for tar2 and several modifications to the par file.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">Also, this option (method 2) will not necessarily give the same results as the first approach I mentioned (method 1). It depends on the tables. For example, a table of 95% Al and 5% C (method 1) may have different
opacities and other properties than effectively taking a weighted average of a Al table and a C table (method 2).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">One way would be to define another species. So when you run setup, you could specify species as species=tar1,tar2,cham. Note that species names have to be 4 letters in FLASH.</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt">tar1 would be the pure aluminum</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">tar2 would be aluminum with some % of carbon</span><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt">cham is helium in the default LaserSlab setup</span><o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt">You’d need a new EOS table for tar2, and you’d need to at the very least modify the par file and Simualtion_initBlock to place the various species at the desired initial positions.</span><o:p></o:p></p>
