Performance with Radiative Transport #565
-
|
I realise this question is likely to be highly specific to the problem at hand, but does anyone have even rough predictions for the additional cost of non-relativistic radiation transport? Obviously there are more equations that need to be solved, but I was wondering how much more intensive it is compared to a simulation with a general equation of state and no magnetic fields. Best information I could find was in RT code paper (link) but there the comparisons are made between magnetised relativistic simulations, I am only looking in making the jump from Newtonian hydro to Newtonian hydro+RT. |

You are looking at the wrong code paper. If you want to use the non-relativistic RT, check out the documentation here: https://github.com/PrincetonUniversity/athena/wiki/Non-relativistic-Radiation-Transport The cost will be very problem dependent and how many angles you need to use. But it can vary from 4 to 10 times the hydro. |
