<div dir="ltr"><div><div><div>Hi everyone,<br><br></div>It looks to me like this issue was never resolved - for instance when I attempt to save the clump hierarchy (which I can now find thanks to Kacper!), it complains about not finding NumberDensity (traceback here: <a href="http://pastebin.com/NSuaj8XH" target="_blank">http://pastebin.com/NSuaj8XH</a> ). I got it to work using a potentially non-optimal solution, namely adding the following lines to the end of yt/frontends/flash/fields.py -- <a href="http://pastebin.com/jYWcZCDj" target="_blank">http://pastebin.com/jYWcZCDj</a><br>
<br></div>I can imagine this failing if the dataset uses the Helmholtz EoS or maybe with multispecies, but maybe it would work (I don't have any datasets handy which use these).<br><br></div>Thank you,<br>John<br><div>

<div><br></div><div>Basically, we would need to pare the FLASH data dumps, search for the appropriate runtime parameters that control the EOS settings (as described in section 15 of the FLASH docs: <a href="http://flash.uchicago.edu/site/flashcode/user_support/flash4_ug/node22.html" target="_blank">http://flash.uchicago.edu/site/flashcode/user_support/flash4_ug/node22.html</a>), and from that back out what mean molecular weight is.</div>
