<div dir="ltr">Hi Maria,<div><br></div><div>There are many possible causes for a con2prim failure, but generally if unphysical conservatives are input then failures are inevitable. The information provided doesn't tell us much. I've always included a super verbose error output when a failure occurs within my own con2prim implementations, so that I can backtrace any problems. It would be useful to see if this feature either exists (and can be enabled with a parameter file setting) or could be added.</div><div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div style="font-size:12.8px">-Zach</div><div style="font-size:12.8px"><br></div><span style="font-size:12.8px">* * *</span><br style="font-size:12.8px"><span style="font-size:12.8px">Zachariah Etienne</span></div><div><span style="font-size:12.8px">Assoc.

Any inkling of why this might happen? I tried with both ppm and weno recon_method, and with higher refinement. </div>
