<div dir="ltr"><div class="gmail_quote"><div dir="ltr"><div>Hello everyone,<br></div><div><br></div><div> I'm curious if someone with experience with the MultiTemp aspect of FLASH's EOS module, in particular (but not necessary) the MatRad3 case which sets the ion component to zero, could help me understand it better. I am trying to implement a new EOS that works within MatRad3. I have this EOS working with Multispecies, but for the MatRad3 scenario I'm a bit confused about when the NR solver needs to be called (so Table 15.1 in the user guide).</div><div><br></div><div> Why does the Newton-Raphson solver need to be called in the MODE_DENS_EI cases in Gamma and Multigamma, given that eint is solved analytically in the case of MODE_DENS_TEMP. Why isn't temp set just with the inverse? My confusion makes understanding the more complex MODE_DENS_EI_{ } submodes quite difficult. </div><div><br></div><div>Also, do I have much control beyond Simulation_initBlock in how EOS will be called throughout the simulation, where we are including RadTrans and Diffusion. It seems like for the most part it's limited to MODE_DENS_EI, but there are some other cases, including _EI_MAT_GATHER_PRAD_SCALE (hy_uhd_unsplit), and _PRES (hy_uhd_getFaceFlux). </div><div><br></div><div>I very much appreciate any guidance.</div><div><br></div><div>Cheers,</div><div> -Mark</div><div><br></div><div>-- <br><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><br></div><div dir="ltr"><span style="font-size:12.8px">Mark Richardson</span><br style="font-size:12.8px"><div style="font-size:12.8px">Beecroft Postdoctoral Fellow, Department of Physics<div>Denys Wilkinson Building - 555F</div><div>University of Oxford<div><a href="mailto:Mark.Richardson@physics.ox.ac.uk" target="_blank">Mark.Richardson@physics.ox.ac.uk</a><br><div><a href="tel:%2B44%201865%20280793" value="+441865280793" target="_blank">+44 1865 280793</a></div></div></div></div></div></div></div></div></div></div>
