<div dir="ltr"><div><div><div>Dear Slah,<br><br></div> there is a default parameter that sets the minimum density (and e and p, etc) that can happen. The default value, I believe, is 1e-10. It's called sml_rho (there's also small_e, small_p I believe). You could set this to a lower value in your flash.par file. <br><br></div>Cheers,<br></div> -Mark<br><div><div><div><div class="gmail_extra"><br><div class="gmail_quote">On 2 July 2018 at 13:31, Slah Abdellaoui <span dir="ltr"><<a href="mailto:slah.abdella@gmail.com" target="_blank">slah.abdella@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Dear All</div><div>I am running a problem, where the initial density is proportional to 1/r^2, whenever I change the parameter the density profile reaches the of 1e-10 (figure dens.png) and it doesn't go further, as it suppose to vary as a function of 1/ r^2.
