AmunPy 1.0.0 Released

I am pleased to announce the release of AmunPy 1.0.0, the first stable version of the Python interface for reading and analyzing AMUN Code simulation snapshots. This release represents a complete rewrite and modernization of the package, providing a clean, tested, and well-defined API for both 2D and

Update: Code Repositories Now Hosted on GitLab

The development of the GODUNOV and AMUN codes is now hosted on GitLab, which serves as the central platform for source code management, release distribution, and user support. All official versions of the codes are maintained in public Git repositories, providing access to the complete development history, tagged releases, and

The code repository moved to Bitbucket

The GODUNOV code repository has been moved to Bitbucket. You can find it under the GODUNOV Code project. This repository is public, so anyone is welcome to clone it and contribute to the code. Grzegorz

The GODUNOV code version 2.5

Another update of the GODUNOV code to version 2.5 with important changes: * in the new time step estimation include the acceleration from source terms, such as forcing or gravity; also print the time step limit resulting from the acceleration in the integral file, * implement magnetic field discontinuity detection in

Release of the GODUNOV code version 2.4

A new update of the GODUNOV code version 2.4 with several fixes: * more general default host file to support more compilers, * rename bext(:) to buni(:) for the uniform magnetic field components, * new parameter 'dtres' to determine the real time interval for storing the restart dumps, * new parameter

Quick update of the GODUNOV code to version 2.3

A new quick update of the GODUNOV code version 2.3 with just a few fixes: * make the default host file work with the GNU Fortran compiler, * add several variable checks in makefile and inform user if the compilation environment is incorrect, * add parameter files for a few basic test

The GODUNOV code updated to version 2.2!

A new update of the GODUNOV code version 2.2 with a few new features added and several fixes: * add hyperbolic div(B) source terms to GLM-MHD (option HEGLM), * store primitive variables in restart files too (this fixes problems in some situations with job restarting), * improvements to reconstructions LimO3 and

The GODUNOV code updated to version 2.1!

A small update of the GODUNOV code to version 2.1. * optimization of the boundaries, * current density is calculated in sources now. Feel free to download the source code from the page Download and if you have any problems or questions, give me a feedback.

The release of the GODUNOV code version 2.0!

The next version 2.0 of the GODUNOV code has been released. The changes with respect to the previous version are listed below. * hyperbolic divergence cleaning using the GLM-MHD equations and EGLM-MHD equations, * improved the code for shock detection, * parameter file checker, * the reduction of memory utilization, * bug fixes. Feel

The GODUNOV code version 1.0 released!

Finally, after more that 5 years, I have prepared a version 1.0 of the GODUNOV code, a uniform mesh version of the AMUN code. The list below specifies what the current version of the code supports. * rectangular (Cartesian) domain in 2D and 3D, * hydrodynamical (HYDRO) and magnetohydrodynamical (MHD) equations,

Welcome to the AMUN code website!

AMUN is a code to perform numerical simulations in a fluid approximation on uniform or adaptive meshes with and without magnetic field. The goal in developing this code is to create a solid framework for simulations on uniform and adaptive meshes in the Cartesian, cylindrical, or spherical coordinate systems with
