Not sure if the 1.6 mbar stated as a comment in the par file is correct or not, but you can check the output. You can look at the various pressures by plotting "pele", "pion", and "prad". The default units in FLASH should give these in erg/cm^3, which is equivalent to ubar. </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, May 31, 2020 at 4:10 AM kouider benbayer <<a href="mailto:benbayer.kouider@gmail.com">benbayer.kouider@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi all<br><div>First, thank you in advance for the help<br>In example.par file the defaults Chamber pressure for Helium is 1.6 mbar. <br>For understand how pressure change with the temperature and density.
