<p>Hi,</p>
<p><br>
</p>
<p>I'm a bit confused as there are multiple EOSs and multiple tables.</p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Is the following the case:</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><font size="3">- The </font>simulation using the original LS220 table and without bypassing the abort stops just before bounce (your original question)</p>
<p><font size="3">- The </font>simulation using the higher resolution LS220 table and without bypassing the abort also stops just before bounce
<br>
</p>
<p><span style="font-size: 12pt;"></span><span style="font-size: 12pt;">- The simulation using the higher resolution LS220 table</span><span style="font-size: 12pt;"> and with bypassing the abort runs fine and doesn't abort at all. </span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Have you tried the original LS220 table with the abort bypass? I suspect this will work just as well as with the higher resolution table.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">- </span><span style="font-size: 12pt;">T</span><span style="font-size: 12pt;">he simulation using the original LS375 table </span><span style="font-size: 12pt;">and without bypassing the abort</span><span style="font-size: 12pt;"> crashes
after bounce with similar error to the original you shared in first email.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Have you tried the original LS375 table with the abort bypass?</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p>EOSmaker takes tabulated EOSs and puts them in the HDF5 format we use, also generating some extra derivatives we use. The original LS EOS come from a code, not a table, so EOSmaker is not used to make those tables. I have a code that runs the LS code to
generate our tables. It is not online anywhere and it has also been 10 years since I used it. I can try to find it and make a similarly higher resolution table, but I think if you need to bypass the abort anyways, and if that alone works, then I wouldn't
need to.</p>

<p>Hi,</p>
<p><br>
</p>
<p>Sorry for the silence, I haven't had a chance to look at this till now. </p>
<p><br>
</p>
<p>The point this is failing at is not near the edge of the table (rho~1.77e14g/cm^3, temp~3.5MeV, and ye=0.278), however, in energy space it is very close to the edge. For that density and ye, I've attached a plot of the internal energy vs temperature and
there is no temperature where it equals (logged, cgs) 19.5587, so the EOS cannot be inverted (the hydro solver gives the EOS an energy and the EOS has to find the temperature that corresponds to it).</p>
<p><br>
</p>
<p>We have a different LS220 table that we use for FLASH, I've added it to the page you linked (it was there before, but I missed it when moving the data around). It has a slightly higher resolution in density and temperature. It may give better results, especially
given that we use this for some reason (I forget now, it is a decade old). <a href="https://su.drive.sunet.se/index.php/s/EGP7wFx4XCLT37G" target="_blank">https://su.drive.sunet.se/index.php/s/EGP7wFx4XCLT37G</a></p>
<p><br>
</p>
<p>If this doesn't work (we still have issues like this some times with some progenitors) you can do what Naveen suggested. With the nuclear EOS it is a bit harder since just because the minimum energy (logged, cgs) for this rho and ye is 19.5599, at other
rho, ye pairs it will be very different. We accomplish this by bypassing the abort on L162 source/physics/Eos/EosNuclear/eos_nuclear.F90 and calling the EOS with the incoming temperature instead of the incoming energy, this avoid the inversion. It essentially
pumps internal energy into the zone, so be careful with it. We have a parameter file flag to turn this on and keep track of any such calls to ensure we don't do it too often. When it does occur it is in the situation you have now, right at bounce. </p>
<p><br>
</p>
<p>Also, FYI, I had suggested changing the file io_intfTypesModule.F90, not Flash.h, you should never edit the Flash.h as it get re generated with each setup.</p>

<div dir="ltr">Dear all FLASH users,<br>
I tried to run 2D supernova core collapse for two different nuclear EOS of Lattimer and Sewsty (<a href="https://ttt.astro.su.se/~eoco/eos.html" id="gmail-m_7261513257979920782LPlnk806626" target="_blank">https://ttt.astro.su.se/~eoco/eos.html</a>) with K=180
and K=220 but I got the errors which I attached the images of them.<br>
for the case of k=220 it runs into problem after 231 ms (it seems before the bounce) and for k=180 just after 24 ms<br>
Could anyone tell me what I have done wrong? <br>
(changing the resolution also did not resolve the issue)<br>
<br>
P.S. Trying to compile the FLASH, I also changed the Flash.h file and replace the line as Dr. O'Connor proposed:<br>
