Dear Roland, Thanks for your reply.
For the previous question about r-process, I found a document(https://stellarcollapse.org/media/micra2013/moesta.pdf) saying that GRHydro could consider neutrino leakage. But I have no ideal how to implement it. Is there any suggested way to deal with neutrino leakage with GRHydro (or other thorns) ? Thank you. Best regards, Chia-Hui ________________________________ 寄件者: Roland Haas <[email protected]> 寄件日期: 2018年10月2日 下午 09:11:21 收件者: 林家暉 副本: Einstein Toolkit Users 主旨: Re: [Users] mass estimation of neutron star Hello Chia-Hui, > In addition , I would like to ask question about computation > consumption.

For example running on 32 cores will make it run slower but not by a factor of 48/32 so that the total resources (number-of-cores * hours-used) goes down. You could also try reducing (slightly!) the resolution eg by a factor of 1.25 which would make the simulation cheaper (but also loose significantly in accuracy). Finally you could try and make the simulation domain smaller, which safes a bit but not a whole lot usually. You can also try and see if reducing the amount of output produced makes any difference (though that is unlikely). This is the outXXX_every parameters and generally everything with an _every in its name. Yours, Roland -- My email is as private as my paper mail.
