Re: Gadget4 hangs with a zoomed-in IC

Hi Weiguang,

Hm, this is interesting. The group finding via FoF/Subfind has fully completed, but then the code appears to hang in writing the group catalogue to disk in the function subfind_save_final().

Could you perhaps try to switch off ALLOW_HDF5_COMPRESSION? (just a guess)

Otherwise, since the problem is reproducable, it could also be an issue in the code logic related to the different particle types you have. To examine this, could you make your restart files available to me somehow?

Best regards,

It seems that the program can not write group catalogues for this particular output redshift. I have checked several things: previous outputs are fine; there is no problem with my disk space or the memory cost; I have tried to tune several parameters, but it always hangs at the same step; the zoomed-in IC runs fine with GIZMO.
