<div dir="ltr"><div><div><div>Hi Roland,<br><br></div>Yes, the routines of PPM for "poly" are highly suspicious. I can't make comparisons for the different numbers but the star didn't rotate very fast. The evolution pattern (e.g. rho.max) was different, resulting in a black hole with an wrong mass, contrary to the case with the velocity reconstruction. I'm sorry I can't continue the test at the moment but MP5+Ideal EOS was also good without showing any difference.<br><br></div>Yours,<br><br></div>Hee Il <br><div><div><div><div><div class="gmail_extra"><br><div class="gmail_quote">2014-12-05 16:23 GMT+09:00 Roland Haas <span dir="ltr"><<a href="mailto:roland.haas@physics.gatech.edu" target="_blank">roland.haas@physics.gatech.edu</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello Hee Il,<br>

</div></div>Just to be very sure: you see these issues only when using polytropic<br>
EOS, ie Ideal_Fluid EOS is fine? I am asking because for some of the<br>
routines there are two copies, a Ideal_Fluid one and a 2D_Polytrope one<br>
and only the later would contain the possible bug if you only see it for<br>
polytropes. Note that reconstruct_Wv does (by design) give different<br>
answers than the direct velocity reconstruction, in particular when the<br>
velocities are high. Are the "different" numbers you see "obviously wrong"?<br>
<br>
Yours,<br>
Roland<br>
