<p>Hi Malia,</p>
<p><br>
</p>
<p>Usually this indicates that your abundances have gotten corrupted
in some way. There are various ways that this can happen,
depending on what kind of simulation you are running.<br>
</p>
<p><br>
</p>
<p>If you are using the built-in nuclear networks, NaNs are not
capture quite properly. I have a patch for that if that is what
you are using (attached). If you aren't using the nuclear
networks, then the problem is likely somewhere else.</p>
<p><br>
</p>
<p>Hopefully that helps some. If you say a bit more about your
simulation someone might be able to make a better guess at what
might be going on. There are lots of problems that can manifest
this way.<br>

<div>I am getting the following error from the helmholtz
eos about negative pressure:<br>

I know that the initial mass fraction supplied to the eos
is correct. The initial call of the eos sets abar and zbar
correctly. I am not sure what is causing them to error. I
also don't know why I am getting a NaN for the electron
Pressure. Could anyone help point me to what is going
wrong and how I can solve it?<br>

Thanks,<br>
