【Course Objectives】

The primary purpose of the lectures is to acquire the basic knowledge of Numerical Relativity and to learn its application to multimessenger astronomy. Particularly, the goal of this lecture is to learn the basics of the formulation problem in Numerical Relativity, the basics of numerical hydrodynamics, and the basics of numerics.

【Course Contents】

In this lecture, I will begin by reviewing the recent progress of multimessenger astronomy and understanding the scientific background of this topic. Particularly, I will focus on why we need numerical relativity in the multimessenger era. In the first half, I will explain the formulation problem for solving the Einstein equation and introduce the 3+1 decomposition. Then, I will review the pathology of this formulation and introduce the reformulation by Baumgarte, Shapiro, Shibata, and Nakamura. Also, I will introduce the basics of hydrodynamics and techniques on how to solve the equation numerically. Then, in the final part, I will introduce its application to numerical modeling of gravitational wave sources.
