<div dir="ltr">Hi Ed,<br><br>Apologies for the late reply; this email went to my spam folder, which I check irregularly. I don't think cosmic rays have ever made it to a public FLASH release. Karen Yang & Mateusz Ruszkowski developed a cosmic ray module in FLASH. You can find additional details in:<br>Yang et al. 2012, 2013 and Yang & Ruszkowski 2017.<br><br>Since cosmic rays are now part of the public Athena++ release, they might be willing to share their implementation. It's still in FLASH4.2.2, but one of my goals for September is to port to FLASH4.8. All of that is one-moment transport (both diffusion and streaming). It would be nice to have two-moment in FLASH, perhaps leveraging HYPRE, etc.<br><br>Best wishes,<br><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr">--------<div>Ryan</div></div></div></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Aug 28, 2024 at 12:58 PM Ed Buie <<a href="mailto:ebuie@vassar.edu" target="_blank">ebuie@vassar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello Flash users,<div><br></div><div>I was looking through the documentation and while I didn't see any indication of it, I was wondering if there are any schemes for cosmic ray transport that have been developed in FLASH? </div><div><br></div><div>Thank you!<br clear="all"><div><br></div><span class="gmail_signature_prefix">-- </span><br><div dir="ltr" class="gmail_signature"><div dir="ltr">-Prof. Ed Buie II</div></div></div></div>
