Numerical simulations with PLUTO code

by Dr. Miljenko Cemeljic

 

Abstract: Aim of the lectures is to guide attendants to active using of the PLUTO code. We will work in 5x2 hrs blocks: each hour of theoretical exposition will be followed with an hour of hands-on work with the code. We will start with a brief introduction to numerical simulations in astrophysics and position of the PLUTO code with respect to other codes. After short description of numerical methods employed in the code, we will proceed with installation of the code, testing of the installation and initial visualization of the results with gnuplot. Next we will set a purely hydrodynamic accretion disk in 2D, and learn to use more advanced visualisation tools like Paraview and VisIt. I will also show the use of Python for visualisation. On the example of adding the magnetic field in the accretion disk simulation, we will next learn the basics of the magneto-hydrodynamic simulations, both in ideal and non-ideal (viscous and resistive) approach. I will show how to use a Linux cluster for simulations, and how to plot the magnetic field lines. In the last lecture, we will learn setting of the full 3D magnetic accretion disk and visualization of the results.

Prerequisites: minimal working knowledge of Linux, on the level of using the terminal in CAMK system. Login in CAMK or similar system or a laptop with Linux partition, with access to C compiler and working Python, will be necessary to fully participate in hands-on part of the lectures.
