Accretion problem setup:

This version of Athena++ generates parameterized CCSN accretion models.
jobscript_parallel_main or jobscript_serial_main run a default accretion model that uses the following: 1) Lnu=40 (in units of $10^{51} \mathrm{ergs} \mathrm{s}^{-1} \mathrm{g}^{-1}$ ) 2) Mdot=0.7 (in units of $M_{\odot} \mathrm{s}^{-1}$) 3) Mach=2.0 4) RPNS=30 (in units of km) 5) enue=12.6156 (in units of MeV) 6) enueb=18.9234 (in units of MeV) 7) Tau=2/3 8) Boundary conditions described in Pochik and Thompson 2025 (https://arxiv.org/abs/2411.16857)
Variables in the athinput files already include the default boundary values and conditions listed above.
The accretion_12panel.py plot script produces a plot of the accretion model at the final timestep.
jobscript_parallel_thermal runs the code used for the accretion model analysis in Section 3.6 of Pochik and Thompson 2025 using the following: 1) Lnu=10 (in units of $10^{51} \mathrm{ergs} \mathrm{s}^{-1} \mathrm{g}^{-1}$ ) 2) Mdot=0.3 (in units of $M{\odot} \mathrm{s}^{-1}$) 3) ```Sout=3.(in units of $k_{\mathrm{B}}$ baryon$^{-1}$) 4)vcoef=0.8(fraction of free fall) 5)Yeout=26/566)Abarout=56.7)RPNS=30(in units of km) 8)MPNS=1.4(in units of $M_{\odot}$) 9)enue=12.6156(in units of MeV) 10)enueb=18.9234(in units of MeV) 11)Tau=2/3```
