In the 5 months of Fiscal Year 2022, we started with the preparations for the project. We started investigating possible implementations of the proposed idea, but could not test them thoroughly yet.We have prepared the setup for performing our simulations of general-relativistic hydrodynamics for binary neutron star mergers. In particular, we have been checking the correctness and accuracy of the tabulated equations of state and of the codes to read them in our main code for binary evolution.The fellow is becoming familiar with the complex codes we use, has been granted access to two supercomputer facilities, has familiarized with them, and has prepared the computational environment on them.

在2022财年的5个月里，我们开始了项目的准备工作。我们开始研究提议的想法的可能实现，但还不能彻底测试它们。我们已经准备好了进行双中子星合并的广义相对论流体力学模拟的装置。特别是，我们一直在检查状态方程表的正确性和准确性，以及在二进制演化的主代码中读取它们的代码。这个家伙对我们使用的复杂代码越来越熟悉了，他已经获得了两台超级计算机设备的访问权限，熟悉了它们，并在它们上面准备了计算环境。
