Dear Modecai,
<div class="">Thank you very much for your mail it is indeed very helpful. I have found the article related to FERVENT on the arxive but it doesn’t seem that the code could be found somewhere. Do you know where can we find it please? </div>
<div class="">I would indeed like to try to participate to your Torch groupe meeting :)</div>
<div class="">Thank you again!</div>

Dear Flash users,<br class="">
I am writing to ask about the ways to simulation photoionizations in FLASH. I have gone through the user guide, it seems that the actual ionization methods implemented in FLASH are by collision temperatures. Is there any modules about photoionization? Or, is
there someone have experiences about how to implement it?<br class="">
Thank you a lot<br class="">
C?line<br class="">

Dear Céline,</div>
<div class=""><br class="">
<div class="">The MORAY method of ray-tracing for photoionization relying on HEALPIX pixellation of the sphere (Wise & Abel 2009) was implemented into Flash in the FERVENT module (Baczynski et al. 2015). A simplified version of this algorithm (only following
H photoionization) is included in the TORCH framework, which integrates Flash into the Astrophysical Multipurpose Software Environment (AMUSE) alongside N-body and stellar evolution codes (Wall et al. 2019, 2020). Torch is publicly available at <a href="https://torch-sf.bitbucket.io/" class="">https://torch-sf.bitbucket.io/</a>,
and we invite users to join our mailing list and weekly users-group meeting on Zoom as well.</div>
<div class=""><br class="">
</div>
<div class="">Another approach implemented into Flash by the SILCC group (Walch et al. 2015) was TreeCol (Clark, Glover, et al. 2012). This was described as TreeRay by Wünsch et al. (2021), which I would certainly recommend as useful reading and insight into
what may be available to use.</div>
