<p>Dear Kiyarash Taghiniyarami,</p>
<p><br>
</p>
<p>The first error (for LS180) seem to indicate a lack of storage space on your drive. </p>
<p>You see this written by the error handler in your first screenshot. Make sure that there is space</p>
<p>and that you are not trying to create files larger than the maximum filesize allowed by your system. </p>
<p><br>
</p>
<p>The second errors seems to be related to physics. During bounce things change very fast and it </p>
<p>might be that you need to reduce your timestep during this time. However, I am not sure about this</p>
<p>because I do not know exactly how flash regulates the timestep. The error is in the EOS module where the</p>
<p>routine fails to converge, I have seen this happen around bounce and for me it always helped to restrict dt or</p>
<p>the resolution. However, I was working with an other code at the time.</p>
<p><br>
</p>
<p>Best,<br>
Haakon Andresen</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_1816844387868435849LPlnk532912" 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>
