The Spritz code is a fully general relativistic magnetohydrodynamic code based on the Einstein Toolkit. To use it, uncompress the tarball (tar xvf SpritzCode_v1.1.0.tar) and then follow the instructions in the README file.
Version 1.1.0 introduces full support for finite-temperature equations of state and neutrino leakage. It includes also a thorn to read initial data produced with Nrotstar (LORENE) and a set of python scripts to slice finite-temperature tabulated equations of state.
Prerequisites: if working with initial data computed with LORENE using an equation of state (EOS) in CompOSE format (such as those available with Cipolletta et al 2021), you should use a version of Lorene published after March 2019 since older versions (including the ones coming with the Einstein Toolkit) have a bug when reading that EOS format. You should therefore install LORENE as a standalone library. After having installed LORENE and downloaded the Einstein Toolkit, before compiling Spritz you should add the following two lines to your configuration file (for example, Cactus/simfactory/mdb/optionlists/generic.cfg if compiling on your laptop) in order to use your installed version of LORENE and not the one coming with the Einstein Toolkit:
