Spritz is a fully general relativistic magnetohydrodynamic code based on the Einstein Toolkit framework. It can be used to perform simulations of magnetised neutron stars with finite temperature equations of state and neutrino emission (using the ZelmaniLeak code).

The first version of the code was released on Zenodo in February 2020 and the paper presenting it was published on Classical and Quantum Gravity.

A second paper presenting tests with finite temperature tabulated equations of state and neutrino emission has been submitted for publication and the new version of Spritz (v 1.1.0) is available on Zenodo.
