Simulation

Introduction

In this article, I posted about my work on tutorial 4 of Athena++. Here, I post my work on the Rayleigh-Taylor instability challenge in 3D.

Introduction.

Visualization of 3D magnetohydrodynamic simulation results computed in parallel in this post. The visualization is done with VisIt 3.3.3 running on a Mac.

Introduction

Up to this article posted last month, I have confirmed that OpenMPI can be embedded in a Docker container and used for parallel computing on multiple nodes. In this post, I will use the Docker container created above to run tutorial 4 “Running 3D MHD with OpenMP and MPI” of Athena++ on multiple nodes.

Introduction

In a previous post, I summarized the contents of the first tutorial “1D Hydorodynamics and MHD” after installing Athena++. This post is a continuation of that post and summarizes the contents of the tutorial that was executed to perform visualization and other tasks.

Introduction

I have been interested in trying out astrophysics-related simulations for some time, and had been checking out ENZO, GADGET, GIZMO, and others. I happened to know Athena, and when I looked into it, I found that Associate Professor Kengo Tomita of Tohoku University maintains a Japanese page and has some information in Japanese, so I decided to give it a try.

Here, I summarize the process of installing and running the tutorial, and post it.
