<p class="MsoNormal"><span style="font-size:11.0pt">The sesame file that FLASH reads in should be an ascii file (one material per file) in the same format as described in LA-UR-92-3407, which is presumably the document you were already referring to. One of
the limitations in FLASH is that the sesame reader will only work for a 3T simulation, so the material needs tables 303 and 304 which do not exist for every material in the sesame library.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Some people also have access to sesame data for ionization, opacities, transport coefficients, etc., but these are not supported in FLASH. It is worth noting that FLASH will use a Thomas-Fermi model for ionization
when using sesame for the EOS.<o:p></o:p></span></p>
